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.
GREAT!

The idea is that no number from the interval (n/2, n) will ever be a divisor of n.
hi, can you please explain to me why i <= n/2; i somehow get that this is faster than going through every i until it reaches n. but i still don't grasp the idea.
WOW
This is insane!!!
This is why knowing math is helpful for computer science facepalm
It took me 30 minutes and ~ 40 lines of code, and now i see this)
Programming is a pure pleasure
WTF? Are you God in MAth + programming skill
It is a Congruence formula! That's all.
Are you God himself, who descended on earth just to flex his programming skills?
Please write a book, i want to know how you think.
I can't even believe how some people can come up with a solution like this. Damn!! Good job though!
you mean it evaluates to string each loop thus having O(n^2) time complexity
thats super smart
beautiful, I hate this
