I am given N numbers and for them apply M rules about their order. The rules are represented in a pairs of indexes and every pair (A, B) is telling that the number with index A (A-th number) must be AFTER the B-th number - it doesn't have to be next to him. Ex: N = 4 1 2 3 4 M = 2 3 2 3 1 Output: 1234, 4213, 4123, 2134,...
