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.

Hello, I'm a little confused about what this kata requires to do. I understood the task as checking a binary number for divisibility by 7, but the function that is given to us initially does not have any number at the input with which the code will work. Please explain where we get this input number from and what does this kata want from the user in general?
