Well done, good DSA problem on string manipulation anyway

Nice kata, thanks.

Thanks for this kata!
Really enjoyed the simplicity of the challenge — it lets you focus purely on the logic without extra noise.
I went with a Set-based solution to keep lookups clean and efficient, and it felt satisfying to solve it in a straightforward way.
Great little exercise to warm up the brain — appreciate it!

no 'tie' cases in random.. :-/

Added for all other languages (JavaScript, Python, Ruby).

In JS, it is not pointless - it means you can use ^ instead of !== if you wish.

The second paragraph of the description is pointless and should be removed.
