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.

I wish I could find external material to explain what's going on, but I'm struggling to find anything concrete. The operator is called a bit shift operator.
According to Progamiz: "These operators are not generally used in Java" (referring to bitwise and bit shift operators)
What I do know: in this case the operator "^=" will cancel out similar numbers, then will set the sum to the unique number like any other assignment operator.
Can someone explain the solution? thanks!
simple and impressive!
