Given a weighted graph class and a PQInt class, please complete the implementation of the Dijkstras algorithm according to the instructions in the screenshot provided. Be done in python 3.10 or later, please   class WeightedGraph(Graph) :    """Weighted graph represented with adjacency lists."""     def __init__(self, v=10, edges=[], weights=[]) :        """Initializes a weighted graph with a specified number of vertexes.         Keyword arguments:        v - number of vertexes        edges - any iterable of ordered pairs indicating the edges         weights - list of weights, same length as edges list        """        super().__init__(v)        for i, (u, v) in enumerate(edges):            self.add_edge(u, v, weights[i])                    def add_edge(self, a, b, w=1) :        """Adds an edge to the graph.         Keyword arguments:        a - first end point        b - second end point        """        self._adj[a].add(b, w)        self._adj[b].add(a, w)     def…

Note: java

java code will need to return the traversal of the nodes in DFS order, wherethe traversal starts from Node/Vertex 0.When you follow the traversal process as specified - the complexity of the solution will be linear as shown below.Time Complexity: O(V + E), where V is the number of Vertices andE is the number of Edges respectively.Space Complexity: O(V )The linear space complexity would come from the recursion (AKA ”recursionstack”) you employ to traverse the Graph.
