Hi all, I'm new so here's my first question:

I have an array arr[i*YSIZE + j]

i and j increment in a for loop and YSIZE could be any integer value.

What I'd like to know is how you optimise the array so that you get rid of the multiplication "*". Apparently it is possible but I don't know how to do it.

Please help, this problem has been bugging me for a while now!

Thank you all,

Weever~
