And why is that?

Double is used for slicing not indexing

wow!

I think this is the best practice because we replace the rest of the letters with lowerCase

could anyone explain what makes 2*(n-1) option better than n*2-2?

During C programming it's becoming a habit, couse without semicolon in every place where it should be your program won't run

Getting all of them can be very expensive for large arrays with small n.

Such a wow moment when you see a simple elegant solution and you're like dammn why did I overcomplicate the hell out of it :D

damn

The last line of kata description literally asks to modify the input not create a new one

Oooh I understand now, I did something similar but instead i subtracted 360. Thank you so much for such a detailed response!

I've never seen the double colon used for indexing like that. Thanks for the new info.
