a?y

Random takes two values and returns random values based on their types.

When given two integers, generates a random integers in the range !b.

 6?5
0 2 4 1 4 0

When the right argument is an array, makes a random choices from array y.

If a is negative, deals abs a elements from the array without replacement(no repeats of previously chosen elements).
