WebGenerating combinations (subsets) using bitwise operations. The idea behind this algorithm is to mask the positions in an array using bitmask and select only the unmasked numbers. You will notice that each mask (bit combination) is unique, and the number of mask (s) is equal to 2n, ’n’ being the number of elements in the array. If n is 3, then.
