Getting Top 10 Highest Numbers From Array?

Question

I am having a bit of a issue. I have an NSMutableDictionary with 10 NSMutableArrays in it. Each array has somewhere between 0-10 numbers which could each be any integer, e.g. 12

Answer 1

Easiest way, is to sort the array in Descending order, and then grab the first 10 indexes

Or if they are inside dictionaries, iterate the dictionary allValues, grab all the arrays, add all the elements inside a common array, and sort that
