A array : 1 3 0 2 4 9 input: dest-node: A0 output: all the source nodes: (A1, A3, A4) Each element in this array means the steps it can take. Each element can go left or right. So A[1] and A[4] can reach A[0]. A[1] can reach A[4], A[4] can reach A[0], so A[1] can reach A[0]. Output the index of element which can reach A[0].
