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.

There is a function that can be written to work out the palindromes between 1-100000..... I won't spoil that but I am really struggling to calculate the range calculations.
There is another solution. I am trying to work on it now. There is a way to work out how many palindromes there are using a function that I have come up with but I am really struggling to get it to function for a range. 1-1000... works perfectly but I can't work out how to allow for those bounds.
