Contribution Guidelines

1. Read a problem statement from Problem-Statement/
   Example: ps-1.md

2. Create a folder in Solutions/ with:

   • Your GitHub username (or name)
   • _
   • Problem statement number
     Example: johnDoe_ps1

3. Inside your folder, create: level1/ → Step 1 solution
   level2/ → Step 2 solution
   level3/ → Step 3 solution

4. Follow SOLID principles in every level.

5. Include a README.md in your folder explaining:

• How your solution follows SOLID
• Design decisions you made
