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.

Ignore me i've read it wrong
Explane your problem, I can't see it. 21 people done this kata and no one got a problem with first sample test.

In which language?
There is an error in the first sample test, should be asking for Hello world, not Hello World.
Typical.. I put 'y' instead of 'o' as the question specifies haha, thanks anyway
maybe what you want is to compare srt.charAt(i) with 'o' and not 'y'?
I am doing the XO Kata and I dont know why this doesnt return true for the string xoxo I understand why it wont work for capital letters, I havent implemented that yet:
