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.

Why? From the first two I get 50 dollars without giving change. Then they give me $ 50, I give change to $ 25. I have $ 75. Likewise with the fourth, now I have $ 100. And with that $ 100, I can give $ 75 change. What is wrong with my reasoning?
When the last person hands in $100 bill, Vasya does not have enough bills to return the change.
