Lab Details

Difficulty Level: HARD

Problem Statement:

The Floyd Warshall Algorithm is for solving all pairs of shortest-path problems. The problem is to find the shortest distances between every pair of vertices in a given edge-weighted directed Graph.

It is an algorithm for finding the shortest path between all the pairs of vertices in a weighted graph. This algorithm follows the dynamic programming approach to find the shortest path.

A C-function for a N x N graph is given below. The function stores the all-pair shortest path in the matrix cost [N][N]. The cost matrix of the given graph is available in cost Mat [N][N].

Input:

graph[][] = { {0, 5, INF, 10},

              {INF, 0, 3, INF},

              {INF, INF, 0, 1},

              {INF, INF, INF, 0} }

which represents the following graph

             10

         (0)——->(3)

          | /|\

          5| | 1

           | |

          \|/ |

          (1)——->(2)

              3

Output:

Shortest distance matrix

    0 5 8 9

   INF 0 3 4

   INF INF 0 1

   INF INF INF 0
