LeetCode / coding interview solutions
doocs/leetcode is a multi-language repository of LeetCode, 剑指 Offer, and 程序员面试金典 solutions.
Same problem, same approach. Swapping one for another is a config change, not a rewrite.
Drop-in multi-language LeetCode solution collection; pick it if you prefer its JavaScript-centric explanations, still maintained within the last 18 months.
LeetCode Solutions: A Record of My Problem Solving Journey.( leetcode题解，记录自己的leetcode解题之路。)
Solves the same problem with a different architecture or at a different layer. Expect to rewrite the integration.
Illustrated algorithm training and interview experiences; choose for conceptual learning rather than ready-to-run multi-language solutions.
🌍 针对小白的算法训练 | 包括四部分：①.大厂面经 ②.力扣图解 ③.千本开源电子书 ④.百张技术思维导图（项目花了上百小时，希望可以点 star 支持，🌹感谢~）推荐免费ChatGPT使用网站
C++/Python solutions with detailed explanations for medium/hard problems; choose for depth over language coverage, but it skips easy problems.
This repository contains the solutions and explanations to the algorithm problems on LeetCode. Only medium or above are included. All are written in C++/Python and implemented by myself. The problems attempted multiple times are labelled with hyperlinks.
Structured Python algorithm tutorial with LeetCode analyses; choose for guided learning instead of a multi-language solution dump.
⛽️「算法通关手册」：从零开始的「算法与数据结构」学习教程，200 道「算法面试热门题目」，1000+ 道「LeetCode 题目解析」，持续更新中！
Pattern-based LeetCode explanations; choose to learn problem-solving frameworks rather than copy multi-language solutions.
Crack LeetCode, not only how, but also why.
Multi-language animated DSA textbook; choose for learning algorithms from scratch rather than LeetCode solution sets.
《Hello 算法》：动画图解、一键运行的数据结构与算法教程。支持简中、繁中、English、日本語，提供 Python, Java, C++, C, C#, JS, Go, Swift, Rust, Ruby, Kotlin, TS, Dart 等代码实现
Animated algorithm explanations; choose for visual learning of algorithms, not for a multi-language solution archive.
一位酷爱做饭的程序员，立志用动画将算法说的通俗易懂。我的面试网站 www.chengxuchu.com
Algorithm pattern templates in Go; choose to practice by pattern, but it's a guide rather than a multi-language solution collection.
Algorithm Patterns — the most scientific way to practice, the fastest path to an offer. You deserve it~ 算法模板，最科学的刷题方式，最快速的刷题路径，你值得拥有~
Curated FAANG preparation sheets and DSA solutions; choose for structured practice, not a multi-language LeetCode archive.
Dive into this repository, a comprehensive resource covering Data Structures, Algorithms, 450 DSA by Love Babbar, Striver DSA sheet, Apna College DSA Sheet, and FAANG Questions! 🚀 That's not all! We've got Technical Subjects like Operating Systems, DBMS, SQL, Computer Networks, and Object-Oriented Programming, all waiting for you.
An earlier or more limited way to do the job. Still the right call when you need something small, proven, or CPU-only.
Choose for C++/Python solution notes only if you don't need multi-language coverage, but it hasn't been updated in 5.8 years.
:monkey:LeetCode、剑指Offer刷题笔记（C/C++、Python3实现）
Go-only LeetCode solutions; choose if your stack is Go, but it lacks the seed's multi-language breadth.
:memo: LeetCode of algorithms with golang solution(updating).
Python algorithm/LeetCode notes; only if you want Python and can tolerate a 6.7-year-old unmaintained set.
算法/数据结构/Python/剑指offer/机器学习/leetcode
Java-only LeetCode solutions; choose if you need Java, but it's been unmaintained for 1.7 years.
Leetcode solutions
Official C++ source code for the 剑指 Offer book; use only if you specifically need that book's problems, and it's unmaintained.
《剑指Offer：名企面试官精讲典型编程面试题》第二版源代码
C++ solutions to 剑指 Offer; use if you need that specific problem set, but it's old and narrow.

These projects were analysed and named leetcode among their alternatives. The relationship is not symmetric — how leetcode rates them is a separate judgement, made when leetcode is analysed in its own right.
calls leetcode “covers only the algorithms slice: use it for multi-language LeetCode solutions, not for backend, system-design or agent prep.”
