An undirected graph G(V, E) contains n ( n > 2 ) nodes named v

_{1}, v_{2},….v_{n}. Two nodes v_{i }, v_{j}are connected if and only if 0 < |i – j| <= 2. Each edge (v_{i}, v_{j}) is assigned a weight i + j. A sample graph with n = 4 is shown below. The length of the path from v5 to v6 in the MST of previous question with n = 10 is2
