This repository is a comprehensive, educational library of data structures and algorithms implemented in Python 3. It is organized into subpackages by algorithmic category (sorting, searching, graph, dynamic programming, backtracking, bit manipulation, string, tree, math, matrix, compression, streaming, etc.), each containing self-contained modules with clear function signatures, docstrings, complexity analysis, and often multiple implementation variants. The library is installable via pip and intended for learning, reference, and reuse in competitive programming or software development. It is not an application or data pipeline; it has no web server, CLI entry point, or external runtime dependencies beyond the Python standard library. The architecture is a flat library with a shared `algorithms/common` module providing reusable data types (`TreeNode`, `ListNode`, `Graph`) and each subpackage re-exporting its public API through `__init__.py` files. The codebase demonstrates a mix of modern and legacy Python styles, with newer modules using type hints, dataclasses, and doctests, while older modules rely on bare comments and local node definitions. Despite some inconsistencies and minor bugs, the repository is a well-structured, actively maintained collection that serves as a valuable reference for algorithm implementations.
