PS: Eduard, i don't know why u got accepted solving the problem using that algorithm! Perhaps I'm wrong, but I think mine is quicker (you know, generating n*(n-1)/2 numbers, then finding their divisors and cheking what number doesn't divide any id...) and I got T.L.! Anyway, thanks a lot for your a...

Hello. I solved this problem in some other way. If A %m must be unique for all i<=n then |a -a[j]|%m<>0 for all i,j<=n; i<>j! From this I get n*(n-1)/2 numbers and find all their divisors,and then find first number what isn't divisor of any of this numbers. This got AC, but isn't fast! Eduard.

Hello.
This problem also can be solved using 2D matrix or just can be found a formula using PIE.
