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.
It's a 7kyu kata, and users can use array methods to solve it.
Are numbers with 3 different sums (e.g. 87539319 = 167³ + 436³ = 228³ + 423³ = 255³ + 414³) considered as a case where you should return
true

How is this an array kata?

Really didn't like this kata, wouldn't recommend!
Funny one.
It looks like I need to train more the 2d slices/arrays, iteration, fill, empty etc...
C# technical lead and team leader here. This isn't a coding solution, it's mathematical. I struggled with it as I'm terrible at maths so don't worry. It's not really a very good Kata as it's testing your mathematical ability rather than your programming abilities. Its a common misconception that programming is heavily mathematical. It's not and this one is more about knowing mathematical formulae than being a good developer so I wouldn't worry too much. 14 years in the industry and I couldn't do this one without having to research mathematics.
I'm not convinced that was a good use of my time. More of a tricky math question than anything. The coding part is exceedingly trivial.
