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.
You may not be using two for loops here, but by having two variables and resetting them after hitting the end of the list, you are actually implementing an O(n^2) solution.
O(n) solutions mean there is either a single pass or a constant number of passes that the program needs to run over the input to find a solution. Your current approach grows in the number of passes required based on the number of elements in the list.
