An edge in an undirected connected graph is a bridge if removing it disconnects the graph.
Given a graph with node from 1 to n, and a list of integer pairs represent edges, return all the bridges.
Example:
n = 4
edges = [[1, 2], [1, 3], [1, 4]]
Output:
[[1, 2], [1, 3], [1, 4]]
Explanation:
If any of the edges removed, the graph will be disconnected.
Example2:
n = 4
edges = [[1, 2], [1, 3], [2, 3]]
Output:
[]
Explanation:
No bridges.
