🚀 Usage: Add a New Problem

You can quickly generate a new solution file using the helper script new.sh.

Run Command

bash new.sh "<problem-number>. <problem-title>"

or (if the script has execute permission):

./new.sh "<problem-number>. <problem-title>"

⚠️ If you see this error: bash: ./new.sh: Permission denied Run the following command once to grant execute permission:

chmod +x new.sh

Examples

./new.sh "1. Two Sum"
./new.sh "2. Add Two Numbers"
./new.sh "3. Longest Substring Without Repeating Characters"

📖 Notes

Each solution file may include:

• Code implementation
• Approach explanation (in comments)
• Time & space complexity analysis
