Generate the random number 7 times. Sum them all and divide by 5. Theoritically it should be evenly distributed over 1-7. But owing to random number generators characteristics the sum of rand(5) called 7 times may not be perfectly evenly distributed over 1-7. A nice discussion on some neat options is available here - http://stackoverflow.com/questions/137783/given-a-function-which-produces-a-random-integer-in-the-range-1-to-5-write-a-fun
Rejection technique is pretty standard for this and yet simple.

That is why it is called the Present :). http://sites.google.com/site/ramaswamyr --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
