Algorithms: Animation Display 3.0.11

Did you pass the interview algorithm question? Learning algorithm questions take up too much time? Before this, no algorithmic learning method could be so simple and efficient.

It only takes three steps to become an algorithm master:

1. The first step is to read the question;
2. The second step is to play the animation, refer to the subtitles, and understand the ideas and codes;
3. The third step is to read, analyze, and summarize;

Why create an algorithm animation diagram app?

Like many programmers, I have to spend a significant amount of time refreshing my knowledge of algorithms every time I change jobs. During this process, reading solutions is essential. I've often gone through problem solutions provided by experienced individuals online, and I have a particular affinity for algorithm analysis presented through moving pictures or schematic diagrams due to their quicker comprehension compared to text. While exploring these resources, I encountered certain limitations, such as non-interactive animations that cannot be paused, static data that cannot be manipulated, and inconveniences in studying on mobile devices.

Upon encountering some exceptional animations initially, I felt compelled multiple times to implement them in an application using native code. Finally, I committed to creating 70 animations at once.

I envision this app as a tool that aids in swiftly grasping algorithmic concepts and code, enhancing memory retention and learning efficiency. However, it falls short in terms of code execution and submission; for an optimal experience, code entry is still best performed on a computer.

Why are the questions not arranged according to LeetCode numbering?

The current algorithm questions are divided into three primary blocks:

• Linked list, string, array, binary tree;
• Backtracking, greedy, dynamic programming, divide and conquer;
• Sort and classify separately.

I opt for segregating data structures and algorithms for dedicated learning based on knowledge points. For instance, one can focus solely on understanding binary tree structures or delving into dynamic programming algorithms to make concentrated training aiding in enhancing learning efficiency. Prioritizing data structures before algorithms mimics the sequence of theoretical knowledge acquisition.

In terms of algorithms, the current arrangement comprises backtracking, greedy, dynamic programming, and divide-and-conquer.

Reflecting on my own learning journey in data structures and algorithms many years ago, sorting algorithms were the first concepts I encountered. Given the perceived difficulty of sorting at the time has left a lasting impression on me; hence the initiative to establish a separate classification for sorting catered towards beginners.

Pondering the synergy of animation with code and addressing other interactive issues:

• In my personal algorithm learning experiences, grasping ideas often proved manageable; however understanding code snippets posed challenges especially when lacking adequate comments within explanations. To bridge this gap in app interaction design, a code highlighting feature has been specifically integrated; each line of code will illuminate correspondingly as the animation progresses creating a visually appealing experience.
• While animations simplify understanding processes, supplementing these with brief explanations seemed crucial; hence a "subtitle" function exists beneath each animation providing context as different steps are carried out.
• To facilitate replaying animations and addressing setting up test cases: each algorithm page incorporates a playback feature - simplifying test case management involves the implementation of a "reset" button enabling randomization when changing datasets with just a click.
