Python

TheAlgorithms/Python · ★ 225.3K

A large collection of classic algorithms and data structures implemented in Python, built as an educational reference for learning and practicing algorithms.

javascript-algorithms

trekhleb/javascript-algorithms · ★ 196.7K

A large collection of JavaScript implementations of classic algorithms and data structures, where each one has its own folder with code, tests, and a README explaining the theory and further reading links.

C-Plus-Plus

TheAlgorithms/C-Plus-Plus · ★ 34.8K

This is TheAlgorithms/C-Plus-Plus, an open-source collection of algorithm implementations in C++ covering computer science, mathematics, machine learning, and physics, built as a learning resource rather than for production use.

LeetCode-Go

halfrost/LeetCode-Go · ★ 33.8K

A large, well-organized collection of LeetCode problem solutions written in Go, with 100% test coverage and runtime beating 100% of submissions on many problems.
