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.
Actually, it is. There's a reason why every IT student has to take math classes. Try to understand Machine Learning without Statistics, or Image Processing without Analysis, or Computer Graphics without Linear Algebra. Without at least some basic maths, you'll be lost as soon as your solution doesn't work, or when you have to implement something non-standard.
Is n't nnn faster because it isn't calling the power function? But I'm not sure at all
In fact, this is the best kind of solutions everyone should write in their programs. There nothing more fast, optimal and simple than this.
Nope.
Absolutely.
I don't think it's the best solution from programming point of view. Mathematically it's clever. But this solution is not programming at its essence iykwim.
Are you mad?
