How to get the highest number in an array?

Question

How do i establish the highest number in an array of numbers it could be multi dimension or single dimension

Answer 1

[meta, note] Arrays are allocated as contiguous* memory.

Because of this--plus you do not care where in the array that highest value is located--you can walk a multidimensional array as if it were 1-dimensional.
That is, a 3x3 array is 9 elements long, so you can loop from 0..8 and hit exactly the same elements.

* Adjacent, with no gaps
