Day 4: Building a Strong Foundation with Algorithms and Data Structures

Algorithms and data structures form the very backbone of software engineering, serving as the essential tools that empower developers to solve complex problems efficiently and elegantly. At their core, algorithms are step-by-step procedures or formulas for solving problems, while data structures are specialized ways to organize and store data so that it can be accessed and modified effectively. Together, they enable programmers to write code that is not only functional but also optimized for speed, memory usage, and scalability. Mastering these concepts is crucial because they directly impact how well your software performs under different conditions, whether it’s handling large datasets, responding quickly to user inputs, or managing resources in constrained environments.

For beginners, diving into algorithms and data structures might seem daunting at first, but embracing these challenges early on lays a solid foundation for a successful career in software engineering. Understanding how to choose the right data structure or design an efficient algorithm can transform a seemingly insurmountable problem into a manageable task. Moreover, these skills are indispensable when preparing for technical interviews, where companies rigorously test candidates on their ability to think critically and solve problems under pressure. Beyond interviews, a deep grasp of algorithms and data structures enhances your ability to write clean, maintainable code that can adapt and grow with the demands of real-world applications.

Learning algorithms and data structures is not just about memorizing patterns or formulas; it’s about cultivating a mindset of problem-solving and logical thinking. As you progress, you’ll discover how these concepts interconnect and how they can be applied creatively to build innovative solutions. This journey will challenge you, but it will also reward you with the confidence and skills needed to tackle any programming challenge that comes your way. So, let’s embark on this exciting exploration together, unlocking the power of algorithms and data structures to elevate your software engineering journey to new heights.

Key Data Structures Every Beginner Should Know

Understanding data structures is fundamental to becoming a proficient software engineer. Data structures are ways to organize and store data so that it can be accessed and modified efficiently. Each data structure has its own strengths and ideal use cases, and knowing when and how to use them is crucial for writing effective code. Let’s explore some of the most important data structures that every beginner should become familiar with.


Arrays are one of the simplest and most widely used data structures. They store elements in a contiguous block of memory, allowing quick access to any element via its index. Arrays are ideal for storing collections of items when the size is known and fixed, such as a list of student grades or daily temperatures. However, resizing arrays can be costly, as it may require creating a new array and copying elements over.

Linked Lists consist of nodes where each node contains data and a reference (or pointer) to the next node in the sequence. Unlike arrays, linked lists allow dynamic memory allocation, making it easy to insert or delete elements without shifting others. They are useful when the number of elements changes frequently, such as in implementing queues or stacks. However, accessing elements by index is slower compared to arrays because you must traverse the list sequentially.

Stacks are a specialized data structure that follows the Last-In, First-Out (LIFO) principle. Think of a stack like a pile of plates: you add (push) plates on top and remove (pop) the top plate first. Stacks are commonly used in function call management, undo mechanisms in text editors, and expression evaluation.

Queues operate on the First-In, First-Out (FIFO) principle, similar to a line of people waiting for service. Elements are added at the back (enqueue) and removed from the front (dequeue). Queues are essential in scenarios like task scheduling, breadth-first search in graphs, and buffering data streams.

Hash Tables (or hash maps) store key-value pairs and provide very fast data retrieval based on keys. They use a hash function to compute an index into an array of buckets, from which the desired value can be found. Hash tables are widely used in databases, caching, and implementing associative arrays or dictionaries.

Trees are hierarchical data structures consisting of nodes connected by edges. Each node can have child nodes, forming a parent-child relationship. Trees are used to represent structured data such as file systems, organizational charts, and XML/HTML documents. A special type of tree, the binary search tree, allows efficient searching, insertion, and deletion operations.

Graphs are collections of nodes (vertices) connected by edges, which can be directed or undirected. Graphs model complex relationships such as social networks, transportation systems, and web page linking. Understanding graphs is key to solving problems involving connectivity, shortest paths, and network flows.

By mastering these data structures, you’ll gain the ability to choose the right tool for the task at hand, improving both the performance and clarity of your code. Each structure offers unique advantages and trade-offs, and learning to leverage them effectively is a major step toward becoming a skilled software engineer.

When it comes to algorithms, these are the step-by-step instructions or procedures that solve specific problems or perform tasks efficiently. For beginners, focusing on a core set of fundamental algorithms is essential to build a strong problem-solving toolkit that can be applied across many programming challenges.

One of the first algorithm types to understand is sorting algorithms. Sorting is the process of arranging data in a particular order, such as ascending or descending. Common sorting algorithms include Bubble Sort, which repeatedly swaps adjacent elements if they are in the wrong order; Merge Sort, which divides the list into halves, sorts each half, and then merges them back together; and Quick Sort, which selects a pivot element and partitions the array around it. While Bubble Sort is simple to grasp, it is inefficient for large datasets, whereas Merge Sort and Quick Sort are much faster and widely used in practice. Learning these algorithms helps you appreciate different approaches to problem-solving and the trade-offs between simplicity and efficiency.

Another critical category is searching algorithms, with Binary Search being a classic example. Binary Search efficiently finds an element in a sorted list by repeatedly dividing the search interval in half. This algorithm dramatically reduces the number of comparisons needed compared to a simple linear search, showcasing the power of algorithmic thinking to optimize performance.

Recursion is a powerful concept where a function calls itself to solve smaller instances of the same problem. It is particularly useful for problems that can be broken down into similar subproblems, such as calculating factorials, traversing trees, or solving puzzles like the Tower of Hanoi. Understanding recursion deepens your grasp of problem decomposition and elegant code design.

More advanced techniques like backtracking and dynamic programming build on recursion to solve complex problems efficiently. Backtracking systematically explores all possible solutions and abandons paths that fail to meet criteria, making it ideal for puzzles and constraint satisfaction problems. Dynamic programming optimizes recursive solutions by storing intermediate results to avoid redundant calculations, which is invaluable for problems like the Fibonacci sequence or shortest path computations.

Finally, graph traversal algorithms such as Breadth-First Search (BFS) and Depth-First Search (DFS) allow you to explore nodes and edges in graphs systematically. BFS explores neighbors level by level, useful for finding the shortest path in unweighted graphs, while DFS dives deep into each branch before backtracking, helpful for tasks like cycle detection or topological sorting.

By studying and practicing these algorithms, you develop a mindset that balances creativity with efficiency, enabling you to tackle a wide range of programming challenges. Regularly implementing these algorithms, analyzing their time and space complexities, and applying them to real-world problems will sharpen your coding skills and prepare you for both academic and professional success.

Mastering algorithms and data structures is a journey that requires patience, practice, and the right approach. To truly understand these concepts, it’s essential to engage with them actively rather than passively reading about them. One of the most effective ways to grasp how algorithms and data structures work is through visualization. Tools like VisuAlgo and Visualgo.net provide interactive animations that break down complex operations step-by-step, allowing you to see how data moves and changes in real time. This visual learning can make abstract ideas much more concrete and easier to remember.

Practice is another cornerstone of mastery. Platforms such as LeetCode, HackerRank, and Codewars offer a vast array of coding challenges specifically designed to reinforce your understanding of algorithms and data structures. These challenges range from beginner to advanced levels, enabling you to gradually build confidence and competence. Tackling problems regularly helps you internalize patterns, improve your problem-solving speed, and prepare for technical interviews. Writing your own implementations of common data structures and algorithms from scratch is equally important—it deepens your comprehension and reveals subtle details that reading alone might miss.

In addition to hands-on practice, studying real-world applications of algorithms and data structures can provide valuable context and motivation. Understanding how these concepts power search engines, social networks, recommendation systems, and more can inspire you and highlight their practical significance. Supplement your learning with beginner-friendly books like “Grokking Algorithms” by Aditya Bhargava, which uses engaging visuals and clear explanations, or online courses from platforms like Coursera and Udemy that offer structured paths with video lectures and exercises.

Consistency is key. Set aside dedicated time each day or week to study and practice, gradually increasing the complexity of problems you tackle. Don’t rush—building a strong foundation takes time, but the payoff is immense. Join coding communities and forums to ask questions, share insights, and learn from others’ experiences. Remember, every expert was once a beginner, and with steady effort, you’ll develop the skills and confidence to solve even the most challenging problems with ease.

Now that you’ve built a solid understanding of algorithms and data structures, it’s time to take the next step in your software engineering journey by mastering the tools that help you manage and collaborate on code effectively. Tomorrow’s post will introduce you to version control systems like Git and platforms such as GitHub, which are essential for tracking changes, coordinating with team members, and maintaining a clean, organized codebase.

So, let’s embark on this essential step together and lay the groundwork for your success in software engineering!

Importance of Mastering Programming Basics

Mastering the basics of programming is absolutely crucial for anyone starting their journey in software engineering. Think of programming fundamentals as the foundation of a building—without a strong, well-constructed base, the entire structure becomes unstable and prone to collapse. Similarly, without a solid grasp of core programming concepts, advancing to more complex topics becomes unnecessarily difficult, and your ability to write effective, efficient code is compromised.

When you first begin learning to code, it’s tempting to jump straight into flashy frameworks, trendy languages, or building complex applications. However, without understanding the underlying principles, you risk developing bad habits, encountering frustrating roadblocks, and feeling overwhelmed. A strong foundation in programming basics equips you with the tools to approach problems methodically, debug issues effectively, and adapt to new technologies with confidence. It’s the difference between being able to follow instructions blindly and truly understanding how and why your code works.

Fundamental skills such as understanding variables, data types, control flow (like loops and conditionals), functions, and basic data structures are universal across all programming languages. For example, whether you’re coding in Python, JavaScript, or C++, the concept of a loop to repeat actions or a function to encapsulate reusable code remains the same. Mastering these concepts early on means you can transfer your knowledge seamlessly between languages and projects, making you a versatile and adaptable developer.

Moreover, a strong grasp of programming basics enhances your problem-solving skills. Programming is essentially about breaking down complex problems into smaller, manageable parts and then crafting logical solutions. Without a clear understanding of the basics, this process becomes daunting. Beginners often struggle with debugging or optimizing their code because they haven’t yet internalized how different programming constructs interact or how data flows through a program.

Overcoming these early challenges by focusing on fundamentals sets the stage for long-term success. It builds your confidence, reduces frustration, and accelerates your learning curve. For instance, once you understand how functions work, you can start thinking about modular code design, which is essential for writing maintainable and scalable software. Similarly, grasping data structures like arrays or lists opens the door to more advanced topics like algorithms and performance optimization.

In summary, investing time and effort into mastering programming basics is not just a preliminary step—it’s the cornerstone of your entire software engineering career. It empowers you to learn faster, code smarter, and tackle increasingly complex challenges with ease. Remember, every expert developer started with these same fundamentals, and your dedication to mastering them will pay dividends throughout your journey. Embrace the basics wholeheartedly, and you’ll build a career that’s both resilient and rewarding.

Key Programming Concepts Every Beginner Should Learn

At the heart of every software application lies a set of fundamental programming concepts that serve as the building blocks for all coding endeavors. As a beginner, gaining a deep understanding of these core ideas is essential because they form the language and logic that every software engineer uses to create, troubleshoot, and optimize programs. Let’s explore these key concepts in detail, with clear explanations and relatable examples to help you grasp their importance and functionality.

Variables and Data Types

Variables are like labeled containers that store information your program needs to work with. Imagine a variable as a box with a name tag, where you can keep different types of data such as numbers, text, or true/false values. Data types define what kind of information a variable holds. Common data types include integers (whole numbers), floating-point numbers (decimals), strings (text), and booleans (true or false). For example, in a program that calculates your monthly expenses, you might have variables like rent (a number), name (a string), and isPaid (a boolean indicating if the bill is paid). Understanding how to declare and use variables correctly is fundamental because they allow your program to store and manipulate data dynamically.

Control Structures: If-Else and Loops

Control structures guide the flow of your program, enabling it to make decisions and repeat actions. The if-else statement is a decision-making tool that executes different blocks of code based on whether a condition is true or false. For instance, if you’re building a login system, you might check if the entered password matches the stored one; if it does, grant access, otherwise deny it. Loops, such as for and while, allow your program to repeat a set of instructions multiple times, which is useful for tasks like processing items in a list or running a countdown timer. For example, a loop can print numbers from 1 to 10 without writing ten separate print statements. Mastering control structures is crucial because they enable your programs to handle complex logic and automate repetitive tasks efficiently.

Functions and Methods

Functions (or methods, depending on the programming language) are reusable blocks of code designed to perform specific tasks. Think of a function as a mini-program within your program that you can call whenever you need it, which helps keep your code organized and avoids repetition. For example, you might write a function called calculateArea that takes the length and width of a rectangle as inputs and returns the area. Whenever you need to find the area of different rectangles, you simply call this function instead of rewriting the calculation each time. Learning how to define, call, and pass parameters to functions is vital for writing clean, modular, and maintainable code.

Basic Data Structures: Arrays and Lists

Data structures are ways to organize and store collections of data. Arrays and lists are among the simplest and most commonly used data structures. An array is a fixed-size collection of elements, all of the same type, stored in contiguous memory locations. Lists, on the other hand, are more flexible and can grow or shrink dynamically. Imagine a list as a shopping list where you can add or remove items as needed. These structures allow you to group related data together and access elements by their position (index). For example, you might use an array to store the scores of players in a game or a list to keep track of tasks in a to-do app. Understanding how to manipulate these collections—adding, removing, or iterating over elements—is fundamental to managing data effectively in your programs.

Debugging Techniques

No programmer writes perfect code on the first try. Debugging is the process of identifying, analyzing, and fixing errors or bugs in your code. Developing good debugging skills early on will save you countless hours of frustration. Common techniques include reading error messages carefully, using print statements to check variable values at different points, and employing debugging tools available in most programming environments. For example, if your program isn’t producing the expected output, you might insert print statements to verify that variables hold the correct values or that certain parts of the code are being executed. Learning to debug systematically helps you understand your code better and improves your problem-solving abilities.

Together, these programming fundamentals form the essential toolkit every beginner must master. They are the universal language of software development, applicable across all programming languages and projects. By internalizing these concepts, you’ll be well-prepared to tackle more advanced topics and build robust, efficient software. Remember, these basics are not just theoretical ideas—they are practical tools you will use daily as a software engineer. Embrace them fully, practice regularly, and watch your confidence and skills grow exponentially.

This incremental learning builds confidence and ensures a solid grasp of each component before moving forward.

Seeking help and engaging with programming communities can dramatically accelerate your learning. Platforms like Stack Overflow, Reddit’s programming subreddits, or local coding meetups provide invaluable opportunities to ask questions, share knowledge, and learn from others’ experiences. Don’t hesitate to reach out when you’re stuck—often, a fresh perspective or a simple hint can unlock your understanding. Additionally, explaining concepts aloud to peers or even to yourself can deepen your comprehension and reveal gaps in your knowledge.

Building small projects is one of the most rewarding and effective ways to apply what you’ve learned. Projects give context to abstract concepts and provide tangible outcomes that showcase your skills. Start with simple ideas like a to-do list app, a personal blog, or a basic game. These projects encourage you to integrate multiple programming concepts, troubleshoot real issues, and develop a portfolio that can impress future employers. Remember, the goal is progress, not perfection—each project is a stepping stone toward mastery.

Active learning techniques such as writing code by hand, explaining your code aloud, and reviewing your mistakes critically can also enhance retention and understanding. Writing code by hand slows you down, forcing you to think carefully about syntax and logic, which strengthens memory. Explaining your code, whether in a blog post, video, or conversation, helps solidify your grasp and improves communication skills vital for teamwork. Reviewing mistakes with a growth mindset turns errors into valuable lessons, helping you avoid repeating them and deepening your problem-solving abilities.

Patience and persistence are perhaps the most important qualities in your learning journey.

selamat malam rekan-rekan, malam ini saya ingin share pendapat saya tentang bagaimana performa RAM 8 GB di tahun 2018 ini, khususnya di awal tahun 2018. Apakah masih cukup? Apakah kurang?
Sebelum menjawab pertanyaan tersebut, kita harus tentukan dulu skenario seperti apa yang kita harapkan, karena pada dasarnya setiap komputer akan memiliki hasil yang berbeda-beda bergantung pada skenario yang digunakan. 
Dalam kasus ini, saya akan menunjukkan bagaimana saya sehari-hari menggunakan komputer saya. Sehari-harinya saya menggunakan komputer untuk tujuan membuat program, atau istilah umumnya, ngoding. Saat ngoding, biasanya akan ada 2 editor yang saya buka, yaitu Sublime dan Android Studio / Netbeans, tergantung situasi apa yang sedang saya kerjakan. Lalu selain itu saya juga butuh browser digunakan untuk browsing dokumentasi program, atau sekedar mendengarkan musik di youtube atau spotify, namun yang pasti sudah sangat lumrah saya membuka tab dalam browser saya itu lebih dari 10 tab.
Dalam pengetesan kali ini, saya akan coba untuk membuka semua editor yang saya miliki, yaitu Android Studio, Sublime, Atom, Visual Studio Code, dan Netbeans. Saya coba buka semua karena pada dasarnya Android Studio (dan emulatornya) sangat boros ram, lalu Netbeans itu juga berat karena dibangun diatas java, lalu Atom pada dasarnya dibangun diatas chromium jadi seharusnya berat, untuk Sublime dan Visual Studio Code memang ringan, jadi harusnya tidak akan berpengaruh cukup besar. Lalu saya akan membuka browser Google Chrome dengan membuka 19 tab, yang kesemuanya web statis berupa dokumentasi plus satu tab untuk membuka spotify jadi totalnya ada 20 tab.

Dan berikut adalah hasilnya:
Saat pertama load
Setelah semua editor terbuka dan browser juga telah terbuka, seperti itu lah tampilan performa yang digunakan, ternyata dengan semua load tadi, menghabiskan total penggunaan ram sebesar 7 GB, WOW!!!! Saya sedikit kaget, ternyata kalau semua dibuka, bisa sampai segini ya. Karena masih penasaran aplikasi apa saja yang memakan ram cukup besar, dibawah akan saya tampilkan tab Process dari Task Manager.
Tab Process - Percobaan pertama
Dari gambar diatas, kita dapat mengetahui ternyata pelaku utama yang memakan konsumsi RAM cukup besar yaitu Android Studio, Google Chrome, serta Emulator Android. Untuk editor-editor yang lain ternyata memakan RAM cukup sedikit, bahkan rata-rata dibawah 100 MB semua nya. Saya merasa ada yang janggal, mungkin saya harus membuka beberapa file, lalu menambahkan satu baris, saya save, lalu saya hapus lagi yang saya tulis, lalu saya save lagi. saya lakukan ke semua editor yang sedang terbuka, dan hasilnya seperti berikut.
Tab Process - Percobaan kedua
Ternyata, sesuai dugaan saya, saat editor pertama kali load, tidak mengkonsumsi RAM cukup besar, namun seiring dengan berjalannya waktu yaitu semakin banyak tab yang dibuka di dalam editor tersebut, maka akan bertambah pula konsumsi RAM yang dipakai. Namun ada satu kelainan yaitu pada Android Studio, saat pertama kali load mencapai hingga 1 GB, namun saat sudah mengedit malah turun ke sekitar 800 MB. Saya masih belum paham kenapa ini bisa terjadi.Untuk membandingkan lebih nyaman, dibawah saya paparkan tabel saat pertama load dan setelah membuka beberapa tab lalu edit sedikit.

Percobaan 1 Percobaan 2
Android Studio 1162.0 831.0
Netbeans 486.1 542.6
Sublime 2.3 51.4
Atom 66.5 385.1
VS Code 19.5 471.8

Dari tabel diatas, dapat diketahui pada dasarnya semua editor akan memakan RAM sekitar 500an MB, kecuali Sublime yang entah bagaimana hanya memakan RAM 50an MB saja. Khusus untuk Android Studio, seperti yang saya katakan sebelumnya saya masih belum paham bagaimana ini bisa terjadi, karena sesuai dengan rekan-rekannya, seharusnya dengan ditambahkan tab maka seharusnya konsumsi RAM bertambah, namun ini malah berkurang.

Kesimpulannya, apakah RAM 8 GB di 2018 masih mumpuni? kalau skenarionya adalah seperti skenario diatas, yaitu skenario ngoding pada dasarnya masih mumpuni. Hanya saja saran jangan terlalu banyak yang dibuka tabnya baik tab pada browser maupun pada editor. Bagaimana kalau untuk skenario lain? tunggu postingan-postingan selanjutnya.

Sekian tulisan yang bisa saya bagikan, semoga bermanfaat.
Salam.

Seberapa mirip vanesha dan milea?


Seiring dengan hype nya Dilan dan Milea. Saya ingin membahas sekilas menyangkut Milea. Kata Pidi Baiq, pemeran Milea (Vanesha Priscilia) itu terlihat mirip dengan milea aslinya. Secara pendapat pribadi, menurut saya juga mirip sekilas, tapi kalo dibandingkan side-by-side ya gak mirip2 banget. Atas dasar itu, saya bertanya-tanya, berapa persen sih kira2 kemiripan antara Vanesha Pricscilia dengan Milea yang asli?

Sumber Data:
Foto vanesha saya ambil dari alamat berikut: http://sidomi.com/wp-content/uploads/2017/12/Vanesha-Prescilla.jpeg
sampel vanesha priscilia
Foto milea yang asli saya ambil dari akun twitter yang digadang2 milea yang asli yaitu https://twitter.com/MileaAdnan, akan coba saya sertakan 3 sampel disini.
Milea sampel 1
Milea sampel 2
Milea sampel 3

Metode
untuk membandingkan kemiripan sampel foto yang sudah ada, maka saya akan butuh tool untuk membandingkan kedua foto tersebut. Saya menggunakan tool dari Faceplusplus yang bisa diakses melalui alamat berikut: https://www.faceplusplus.com/face-comparing.

Hasil
Data 1 Data 2 Hasil
Vanesha 1 Milea 1 45.622 %
Vanesha 1 Milea 2 49.636 %
Vanesha 1 Milea 2 47.685 %

Kesimpulan
Dari data yang dihasilkan, bahwa secara komputasi dapat kita ketahui bahwa antara vanesha dan priscilia tingkat kemiripannya kecil, terbukti dari hasilnya yang rata-rata masih dibawah 50%. Tapi dari tingkat 50% juga menunjukkan bahwa memang secara sekilas kita akan mengira bahwa si milea dan vanesha itu mirip.
