LeetCode Solutions in TypeScript 🚀

This repository contains my solutions to various LeetCode problems implemented in TypeScript. Each solution includes detailed explanations, time and space complexity analysis, and test cases.

Summary of Solutions

• Easy: 20
• Medium: 15
• Hard: 0

🚀 Features

• Automatically fetches problem details from LeetCode
• Generates structured solution and test files
• Organizes files by difficulty level

🎯 Purpose

• Improve problem-solving skills through code
• Improve my TypeScript knowledge
• Prove to myself that I can do it

🔧 Technologies Used

• TypeScript / Node.js
• Vitest for testing
• Husky for Git Hook
• Biome.js for Lint/Formatter

📦 Getting Started

1. Clone the Repository

   git clone https://github.com/ailtonferrazjr/leetcode_ts.git

2. Install Dependencies

   cd leetcode_ts
   npm install

3. (Optional) Start Fresh

   If you would like to remove all existing solutions and begin from an empty repository:

   npm run init

   • You will be prompted whether you want to remove all existing solutions.
   • If you confirm, the script removes all solution/test files and resets counters to 0 in the README.

4. Add a New LeetCode Problem

   You can add new solutions any time using:

   npm run new

   • You will be prompted to enter the URL of a LeetCode problem (e.g., https://leetcode.com/problems/two-sum/).
   • The script automatically:
     • Fetches the problem details from LeetCode
     • Generates solution and test files
     • Places them into src/ and tests/ respectively

5. Run Tests

   npm run test

   • Uses Vitest to run unit tests for each solution.
   • Great way to verify your solutions are correct and robust.
