LeetCodeAnimation

LeetCodeAnimation is a learning resource that explains LeetCode algorithm problems through animated GIF illustrations. LeetCode is a platform where programmers practice coding interview problems — think puzzles involving sorting, searching, linked lists, trees, graphs, and dynamic programming. The challenge for many learners is that reading a written solution to an algorithm problem often doesn't make the logic click immediately; visualizing the process step by step is far more intuitive.

This repository addresses that gap by providing animated walkthroughs of solutions. For each covered problem, there is a Markdown writeup that includes an explanation of the approach, along with a GIF animation showing how the algorithm progresses through the data — for example, showing pointers moving along a linked list, or showing how elements get sorted one by one. Solutions are provided in Java and C++.

The README is written primarily in Chinese, which reflects the main audience — the repository was created by a Chinese developer and the content is popular among Mandarin-speaking programmers preparing for technical interviews. An English README is also available.

You would use this repository if you are studying algorithms and data structures for coding interviews and find that animated visualizations help you understand and remember how an algorithm works. It's especially useful for visual learners who struggle to trace through code mentally. The covered problems include classics like Two Sum, Merge K Sorted Lists, Valid Parentheses, Binary Tree traversals, sorting algorithms, and many others.

There is no runnable software here — it is an educational reference resource. The primary language is Java (for the solution code), with C++ solutions also included. The animated GIFs are hosted externally and embedded in the Markdown files.
