WebJul 2, 2024 · They have used an adjacency matrix to represent an weighted undirected graphs. According to geeksforgeeks: Adjacency Matrix: Adjacency Matrix is a 2D array of size V x V where V is the number of vertices in a graph. Let the 2D array be adj [] [], a slot adj [i] [j] = 1 indicates that there is an edge from vertex i to vertex j. WebDijkstra Algorithm is a graph algorithm for finding the shortest path from a source node to all other nodes in a graph (single source shortest path). It is a type of greedy algorithm. It only works on weighted graphs with positive weights. It has a time complexity of O (V^2) O(V 2) using the adjacency matrix representation of graph.
