An undirected graph $G(V,E)$ contains $n \: (n>2)$ nodes named $v_1,v_2, \dots, v_n$. Two nodes $v_i, v_j$ are connected if and only if $ 0 < \mid ij\mid \leq 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 $v_5$ to $v_6$ in the MST of previous question with $n=10$ is $11$ $25$ $31$ $41$
