Data Structures and Algorithms Made Easy with Diagrams (Basics)

Data structures and algorithms that developers must know
We'll explain it in an easy and fun way with pictures!

Once you learn the basics ,
You say it determines the code of your life? 🔍

Developer Fundamentals, Data Structures & Algorithms 📖

I always feel sorry for developers who lack the fundamentals and wander around, unsure of what to learn. They seem overwhelmed by the lack of time and the sheer volume of technology they need to keep up with.
While cutting-edge technology is certainly important, fundamentals are even more important in computer science.
If you have a good grasp of the basics, you can easily learn flashy and popular techniques at any time.

Data structures and algorithms are not limited to a specific language or framework.
Even as popular languages and frameworks change, the data structures and algorithms knowledge you learn can be applied.

Developers who need guidance
Anyone OK 🚩

academic

_{Learning in school classes
Data structure/algorithm
It's too difficult and stiff.
Can't you learn it easily?}

Non-major

_{The majors learn a new language,
Also in the framework
You seem to be adapting well...
I'm curious about the secret!}

job seekers

_{If you look at the coding test questions,
I feel like there's a wall and I feel blocked.
I feel like I need to learn something
What the heck is that?}

Efficiency King

_{The code I wrote
Analyze performance,
More efficient and better performing
I want to change it to code.}

People who are just starting out in development often say this.

• “Often, when I’m trying to solve a problem, I feel like I’m floating on a vast ocean.”
• “I try to solve problems by writing codes that come to mind at the time, but I can’t guarantee that the code is efficient .”
• “Even when comparing my code to other people’s, I can’t really tell which code is more efficient.”
• “I feel like there must be some kind of systematic way to do this, but I have no idea how to do it.”

It's natural to immediately translate the thoughts that come to mind into code.
Until you learn data structures and algorithms !

Most problems we encounter can be solved using already known data structures and algorithms. Even if they don't exist, we can quickly solve them by applying the data structures and algorithms we already know.
For those of you who have always felt the need for guidance, I'm confident that data structures and algorithms can adequately fulfill that role.

1️⃣ Prepare data structures and algorithms!

Learn what data structures and algorithms are, and prepare the necessary knowledge and environment before learning about them in earnest.

2️⃣ Learn about data structures!

Let's delve into data structures in earnest. Since this lecture is a basic course, we'll explore and implement relatively simple linear data structures.

3️⃣ Learn the algorithm!

We'll explore and implement a recursive algorithm and an algorithm for sorting linked lists, a type of linear data structure. We'll also explore dynamic programming, a technique that can address the shortcomings of recursive algorithms.
