  • What is the time complexity of Dijkstra's algorithm and why it?

    The time complexity of dijkstra's algorithm can be reduced to O((V+E)logV) using adjacency list representation of the graph and a min-heap to store the unvisited vertices, where E is the number of edges in the graph and V is the number of vertices in the graph.

  • What is the time and space complexity of Dijkstra algorithm?

    This will bring our total time complexity to O(V^2) where is the number of vertices in the graph. Space complexity will be O(V) where V is number of vertices in graph, it is worse case scenario if it is a complete graph and every edge has to be visited.

  • What is the time and space complexity of Dijkstra algorithm?

    Complexity: The time complexity of the Bellman-Ford algorithm is O(V * E), where V is the number of vertices and E is the number of edges.
    In contrast, Dijkstra's algorithm has a complexity of O((V + E) * log V) when implemented using a priority queue.
