Unfortunately this doesn't work because the 7 element ranges might include zero or two of the random samples drawn from n1..n7. For example suppose you get n5=21, n6=29 and n8 = 4, which gives range [22-28]. There is no number in this range. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
