Documentation
randomDraw :: RandomGen g => Int -> Int -> g -> ([Int], g) Source #
Draw \(n\) different random numbers from the set \( \{ k \,|\, 1 \leq k \leq m \} \).
Examples
>>>fst $ randomDraw 6 49 $ mkStdGen 111[40,13,25,27,26,6]
>>>take 5 $ unfoldr (Just . randomDraw 3 100) $ mkStdGen 111[[11,19,76],[63,49,10],[75,42,12],[20,48,78],[40,94,86]]
>>>fst . randomDraw 6 49 <$> newStdGen[17,7,1,18,13,3]
