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.

it seems like if there's a real large string, it's gonna have to fully convert it to upper case and compare. i guess a for loop with an early return false (in case a char is lowercase) would be the best practice in terms of performance
alright i'm sorry
if i enter "6", your code will throw KeyError because 6 % 2 == 2. so i'd rather do
that's genius
