You are given 2^32-2 unique numbers that range from 1 to 2^32-1. It's impossible to fit all the numbers into memory (thus sorting is not an option). You are asked to find the missing number. What would be the best approach to this problem?
Edit: Let's...

Since N is really small, you can use F[i] = k if number i appears k times.
Allow me to introduce) space complexity.
If so, then change that number to one you haven't seen before, and proceed.
