# liuyubobobo/Play-Leetcode

My Solutions to Leetcode problems. All solutions support C++ language, some support Java and Python. Multiple solutions will be given by most problems. Enjoy:) 我的Leetcode解答。所有的问题都支持C++语言，一部分问题支持Java语言。近乎所有问题都会提供多个算法解决。大家加油！：）

## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-02T17:46:02.011165+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3562, "days_push": 1028, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases, no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## Adoption (not part of the score)
Stars 2725, forks 705 (observed 2026-08-28T04:07:15.729718+00:00)

## What it is
A curated collection of solutions to LeetCode algorithm problems, with every problem solved in C++ and many also in Java and Python. Most problems include multiple alternative approaches annotated with algorithmic ideas and time/space complexity analysis.

## Use cases
- prepare for coding interviews with leetcode problems
- find multiple algorithmic approaches to a leetcode problem
- study algorithm solutions in C++
- practice data structures and algorithms
- compare C++ Java and Python solutions for interview questions

## When to choose
- you want well-annotated, multi-approach LeetCode solutions in C++
- you are preparing for technical interviews and want worked examples with complexity analysis
- you follow the author's algorithm courses and want companion code

## When to avoid
- you need a runnable library or tool rather than reference solutions
- you require solutions in languages other than C++, Java, or Python
- you need actively updated solutions for brand-new LeetCode problems

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: developer-tools
- domain: education, programming-languages
- platform: cpp, jvm, python
- tags: leetcode, interview-preparation, competitive-programming, data-structures, algorithm-solutions, coding-interview, algorithms
