[algogeeks] Re: mapping of 2-d arrays
how to use hash table i have a pair (a,b) with which i want to use. if i use hash function like a+nb there will be number of clashes. also , i have tried map stl in some of programs and most of them give TLE. So, is there a better way for this or i have to look a different approach to this.

Represent your pair in some radix system. So Hash=(a*Base + b) mod SomePrime. -- You received this message because you are subscribed to the Google Groups Algorithm Geeks group.
