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.
Any thoughts on figuring out the issue when the dataset is big? I realize that using System.out is the best way but any other faster method? TIA
