How does it work?

This is the magic of number 4! Here's how it works:

1. Take any number
2. Convert it to its English word representation
3. Count the number of letters in that word
4. Repeat the process with the new number
5. Eventually, you'll always reach 4!

For example: 5 → "five" → 4 letters → "four" → 4 letters (Magic!)
