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.

As sl9site said, this code can fail when question mark is in the middle or at the beginning of the string
it worked because the tests was not written very carefully, otherwise, the question mark in the middle of the sentence would not give a positive result (the same with replace)
