pub fn bellmanford()
Expand description

Performs Bellmanford algorithm on a given weighted graph. Prints a graph with shortest distance from one vertex to another vertex.

Input

  • no_of_vertices - Input the number of vertices in the graph
  • no_of_edges - Input the number of edges in the graph
  • source - The source vertex of an edge in the graph
  • destination - The destination of an edge in the graph
  • weight - The weight of the corresponding edge

Output

Prints the shortest distance of the vertices in the graph
