This repository is a large, actively maintained collection of ~1,000 standalone C++ solutions to LeetCode and similar interview algorithm problems, published by the 'codestorywithMIK' YouTube educator. It is organized into ~30 topic folders (Arrays, DP, Graph, Tree, Sliding Window, Segment Tree, Trie, strings, etc.) with per-topic READMEs, difficulty subfolders, and an extensive set of iPad PDF lecture notes accompanying YouTube videos. It is neither a deployable application nor a data/research project: it is a reference/educational code library whose primary consumption path is copying a solution into LeetCode's online judge or studying the annotated approaches. As such it is classified as 'application' only in the loose sense that it consists entirely of source code rather than data artifacts; in practice it is a non-executable solution bank, and this hybrid nature should be understood by anyone evaluating it for reuse.
