Implementation of Kruskal's Algorithm using C language




C Program to implement Dijkstra's algorithm. Dijkstra's Algorithm finds the shortest path with the lower cost in a Graph. Dijkstra's Algorithm solves the Single Source Shortest Path problem for a Graph. It is a Greedy algorithm and similar to Prim's algorithm. Read more about C Programming Language .
