# leetcode | LeetCode Solutions in Java, JS, C & Python3

Algorithm and coding-interview solution archive with runnable single-file examples in Python, C, Java, and JavaScript.

Keywords: leetcode solutions, coding interview python, leetcode c java, algorithm practice, data structures leetcode

## Quick Start

```bash
# Python example
cd ./000.TwoSum/ && python3 Solution.py
# C example
cd ./000.TwoSum/ && gcc Solution.c -o Solution && ./Solution
# Java example
cd ./000.TwoSum/ && javac Solution.java && java Solution
# JavaScript example
cd ./000.TwoSum/ && node Solution.js
```

## Prerequisites

Python 3, GCC, JDK, and Node.js for running the multi-language examples locally.

**IDE:** Open any `000.TwoSum/Solution.*` file in VS Code for quick navigation across languages.

**Browse:** List all problem folders with `ls -d */` from the repository root.
**Search:** Filter by number prefix, e.g. `ls -d 1* */` for problems in the 100–199 range.
**Clone:** Shallow clone with `git clone --depth=1 git@github.com:mythkiven/leetcode.git` for a quick read-only checkout.
**Verify:** Run one language from Quick Start before bulk edits to confirm your local toolchain.
