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.
But that would be much more inefficient: pre-computing the required array is mere memoization and that works better; same goes for defining auxiliary functions outside, so that every time the function run do not need to be recreated.
You could make it a true one-liner by inlining
divs, and alsompoalong with starting values fornanddas arguments to a self-calling function. Even better, I'll bet you could write a sub one-liner that generates prime factors so your solution wouldn't be limited to bases <= 257.It is an extremely efficient solution, plus forcing myself to one-liner is great practice :)
why would you submit code like this?
