    Initialize the solution matrix same as the input graph matrix as a first step.
    Then update the solution matrix by considering all vertices as an intermediate vertex.
    The idea is to pick all vertices one by one and updates all shortest paths which include the picked vertex as an intermediate vertex in the shortest path.
    When we pick vertex number kas an intermediate vertex, we already have considered vertices {0, 1, 2, .. k-1} as intermediate vertices.
