a very inelegant workaround for the repeating numbers problem

Posted by Jody Brown on November 07, 2001 at 11:26 AM

You are right that it is possible to get repeats, just by using them on their own.

I know it sounds inefficient, but you could maintain a vector of "numbers generated so far". Each time you generate a new number, add it to the vector. The inefficiency comes from having to check each vector element and see if the number generated matches any of them. If it does, you will need to generate a new number.

I will have a think about how it could be done more elegantly.
