The Warshall algorithm uses ____ nested loops to compute the transitive closure.

Use Warshall's algorithm to compute the transitive closure of the graph with the following adjacency matrix: 0 0 1 1 1 0 0 1 0 0 0 0 0 1 1 0 Choose the correct values for the unknown variables after each of the four steps for the algorithm. After the first step: 0 0 1 1 1 a1 b1 1 0 0 0 0 c1 1 1 0 [ Select ] After the second step: 0 0 1 1 1 a2 b2 1 0 0 0 0 c2 1 1 1 [ Select ] After the third step: 0 0 1 1 1 a3 b3 1 0 0 0 0 c3 1 1 1 [ Select ] After the fourth and final step: 1 1 1 1 1 a4 b4 1 0 0 0 0 c4 1 1 1 [ Select ]
