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.
In mordern c++ we call it lambda ({statements}). I used the compare function in the Sort STL
Here rbegin() start from last it also called reverse beginning . Same for rend() also . Generally sort function return ascending order sort then descending is just reverse of it .
Thanks
