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.

the operation of extracting the square root of a number and then squaring
it can lead to minor rounding errors due to
working with floating point numbers

why not?
but these are not random number right?
if the look up times in this solution are constant then it looks good to me
I keep forgetting about expansion of arrays in Python. Neat-o!
