This repository is a comprehensive collection of C++ solutions to LeetCode and competitive programming problems, organized by data structure and algorithm topic (e.g., Arrays, DP, Graph, Tree, Sliding Window, etc.). It serves as a study resource for interview preparation and algorithm practice. The codebase consists of standalone solution files, each solving a specific problem, with no shared library or build system. While the solutions are functional and cover a wide range of topics, they are tightly coupled to individual problem statements and lack modularity or test coverage, limiting reusability as independent components. The repository is actively maintained with frequent additions of new solutions.
