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.

Hi,
Great solution. Thought of something similar. But went against it because even the best sorting algo. has O(nlogn) time complexity. So, shouldn't we just use a couple of integers to compare and get it done in O(n) - time, O(1) - space? Just a thought! :)

103 passed - this failed. Seems like a valid pin to me.
Test Failed
Wrong output for "1234
"
Expected: False
But was: True
