Adding a New Problem

If you're adding a new LeetCode problem, follow these steps:

1. Create a new folder inside the root directory with the exact problem name.
   Example: Add_Two_Numbers

2. Inside that folder, create a new subfolder with the name of the programming language (e.g. C, Python, Java, etc.)

3. Add your solution file there (e.g. solution.c).

4. Create a README.md inside the problem folder explaining briefly:

   • The idea of your solution
   • Time and space complexity (optional)
   • Any edge cases handled

5. Update the main README.md file:

   • Add a new entry in the table with:
     • Problem ID (LeetCode ID)
     • Problem Title (with a link to the LeetCode problem)
     • Link to your solution (to this repo)
     • Difficulty

Adding a New Language to an Existing Problem

If the problem already exists, and you just want to add a new language version:

1. Navigate to the problem's folder.
2. Create a new folder for the language (e.g. Python).
3. Add your solution file (e.g. solution.py) and update the README.md in that folder if needed.
4. No need to add a new row in the main table — just add a new link inside the existing row
