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.
the in-build factorial function of math includes that case

Sometimes I have too much time in my hands and I obfuscate my solutions haha
gee man, is it encrypted?
This is why I love codewars so much, I learned a lot from your solution! thanks!
Too complicated, hard to follow
I was looking for something like this, as I thought about regex in the beginning. Liked that!.
I don't understand how's this solution covers the '0!' case in which is suppose to be equal to 1.
Liked you solution a lot! well done!
