Given an undirected Graph, The task is to find the Bridges in this Graph.  An edge in an undirected connected graph is a bridge if removing it disconnects the graph.   (1) Please write the algorithm in the pseudo code. Note that you are allowed to call well known graphic algorithm like BFS, DFS, Dijkstra. In that case, you can write the code like “Run DFS on the graph with the starting node being node u” (2) Analyze the computing complexity of the algorithm
