algorithms

Skills and conventions for an educational algorithms and data structures repository. Use this skill whenever working on algorithm implementations, data structure code, LeetCode-style problems, graph theory, dynamic programming, or any Java-based educational coding project. Trigger on mentions of: algorithms, data structures, graph theory, sorting, searching, trees, DP, BFS, DFS, linked lists, heaps, segment trees, union-find, or any request to write, refactor, document, or test educational code. Also trigger when the user asks to "clean up", "simplify", "document", "refactor" or "add tests" to algorithm code.
