I am writing a program that takes in an ArrayList and I need to calculate all possible permutations starting with a list of zeroes, up to the value in the corresponding input list.

Does anyone know how to iteratively calculate these values?

For example, given [ 1 2 ] as input, it should find and store the following lists:

[0 0], [1 0], [1 1], [1 2], [0 1], [0 2]

Thanks!
