I can't figure out why (["zggtf","dnmqya","xfvwz"],"nbyfdjgzz") expected xfvwz as an answer but not zggtf. We need 8 changes in both cases but zggtf is first in list.

Not a kata issue. 800+ others solved it in haskell, and if you're timing out, it's probably because you're not handling a walk with infinite steps correctly.

Kata is nice but I can't solve it on Haskell. I wrote a very simple code and my pc run it in less than 1 second but here I get a Timeout message.
