[algogeeks] Finding hash collisions without storage

2010-09-27 Thread AdrianW
Suppose you have N strings that can be generated on-the-fly, and you
wanted to discover if a hash function generates any collisions.  Is
there a way to do this without O(N) storage?

u can use log(n)+1 space to do that by using bit string
