    Avoiding duplicates while generating pair of random numbers!

      hi all,

      Consider that I'm generating 50 edges randomly using Random class. The format of the edge will be (source,destination). So if I randomly generate the pair (1,2), it means that my source node is 1 and the destination node is 2 for my edge from 1 to 2.

      I have a function to randomly generate say 50 edges and as and when I generate I display it to a text area.

      Now the issue is, I want to make sure that I don't have duplicate edges. Can someone suggest a way to ensure that ?
