Hi,

Suppose I have a list of numbers, say (a,b....n) i want to generate a unique number say u so that no other list, say (a1,b1... n1) will not give a number u1 and u!=u1 if (a,b...n)!=(a1,b1...n1)

More over (a,b,...n) is same list as (b,a...n), so they should both generate u, ie order does not matter.

Any one has any idea?

What i came up with is (a+b+...n)+(a*b*...*n), can this fail in any time?

Regards,
