Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.
Get started now by creating a new collection.
No random tests.
Hehe, sorry, I thought perfect square would be enough. It's fixed now.
The instructions should be more explicit about the number being passed in, and the condition that it must result in a whole number when the square root is calculated.

Well done on the abundance of fixed tests, am impressed :D
Would be even better if you threw in a few random test cases just to put cheaters off but I doubt this Kata is worth cheating either way.
