Easy kata, ありがとう。
this needs to be <8kyu>
Sorry, but i can't understand what you're trying to ask for.
Are you asking for counting how many "similar digits" are in each square?
i don't understand how we go from "1, 4, 9" for squaring each iteration
to "10, 11, 12, 13, 14, 19, 21" can someone explain this?
