The power++ logic in your code fails because it will only work for odd-length arrays (like 3x3 or 5x5 etc.)

For the case of 3x3:

true false true
false true false
true false true

While, the case for even-sized arrays are (Using 4x4 as an example):

true false true false
true false true false
true false true false
true false true false

is obviously wrong!

Thanks for the help! I will try this :) Yes the image was pretty clear. Great.

Actually, I think that the image explain more than the example🤣🤣🤦🏽‍♂️

Hello there, yep, I did a code similar to yours, and I got the same results, I thought that I was right but in reality I didn't understand what the kata was asking for.

Instead of going this way: 
Matrix[0][0], Matrix[0][1], Matrix[0][2] .... ....

Go with:
Matrix[1][0], Matrix[2][0] .... and so on💁🏽‍♂️

Here's a screenshot of both examples.

Use your calculator, and verify. Hope I helped you.

Read this, and also, If you're posting code like that, mark it as spoiler.

Thanks for this suggestion. I'll try to learn about this new and useful tool for maths.
