Aug 31, 2022 · Dijkstra shortest path algorithm using Prim’s Algorithm in O(V 2): Dijkstra’s algorithm is very similar to Prim’s algorithm for minimum spanning tree. Like Prim’s MST, generate a SPT (shortest path tree) with a given source as a root. Maintain two sets, one set contains vertices included in the shortest-path tree, other set includes vertices not yet included in the shortest-path tree.

Implementing Dijkstra Algorithm. This problem is part of GFG SDE Sheet. Click here to view more. Note: The Graph doesn't contain any negative weight cycle. Input: V = 2, E = 1 u = 0, v = 1, w = 9 adj [] = { { {1, 9}}, { {0, 9}}} S = 0 Output: 0 9 Explanation: The source vertex is 0. Hence, the shortest distance of node 0 is 0 and the shortest distance from node 9 is 9 - 0 = 9.
