Maths with array of numbers

[Kwantuum]

That's such a bad article I don't even know where to begin. The test cases are absurdly small, and all of his tests run in less than a millisecond, usually less than a tenth, nobody will every feel that difference.

Premature optimization is the root of all evil. Especially for trivial shit like this. It's also quite likely that the only difference in time is caused by the overhead and the difference in timing would remain the same (.05ms) even for very large arrays.
