GATE | GATE-CS-2016 (Set 1) | Question 48

Consider the weighted undirected graph with 4 vertices, where the weight of edge {i, j} g is given by the entry
W_ij in the matrix W



The largest possible integer value of x, for which at least one shortest path between some pair of vertices will contain the edge with weight x is ________


Note : This question was asked as Numerical Answer Type.

(A) 8
(B) 12
(C) 10
(D) 11


Answer: (B)
