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.

, which means the last character is included again. So you need to subtract2
.According to documentation, the last index is the index of the first character to exclude, rather than the last one to include
