Depends how many values you have in the array compared with the overall range
of random numbers. If the number of values is small and the random value range
large, a simple "try-check array-retry as necessary" loop is likely to be the
most practical approach - although it'll degrade in performance as the
proportions of the two change and a significant percentage of the range is
marked as "used".
