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.
WOW, nice one :)
It's clever. Can I read how you find this formula? I can write program only with "for"
This is great!, I got it down to one for loop by modifying gauss' sum slighly different. But this is true algebraic problem solving! :)
Don't worry! We've all been there as well. :) Try to turn that frustration into motivation. Also - never stop improving!
I love finally finishing a Kata just so I can see the guys who figured it out on 1 line! Way to go... I'm so bad :(
