Yep. In PHP this programm works when there set 12 digits in round method :)
Anyway the kata is great. Thank you.
In the description, the function is named repeatString but in the solution box and in test cases, it's repeat_str
This kata is for the very beginners, and they can be very confused about such things.

Python version still uses camelCase despite what was said below.
Some language have no random tests.
Python version should not use input as an argument since it is a built-in function. (Why do you let us do that, Python?)
The kata is asking for the function to be named 'findSum', however the tests only pass when it's name is 'find'.
Needs random tests.
The "recursive" requirement is not checked (nor can it be checked) anyway so it's kinda pointless.
Random tests are missing.
Some language versions do not have random tests, e.g Haskell.
