Consider the network shown below. Using Dijkstra's algorithm and showing your work using a table similar to Table 5.1, do the following:a. Compute the shortest path from t to all network nodes.b. Compute the shortest path from u to all network nodes.c. Compute the shortest path from v to all network nodes.d. Compute the shortest path from w to all network nodes.e. Compute the shortest path from y to all network nodes.f. Compute the shortest path from z to all network nodes.Step N' D(v), p(v) D(w
