1192. Critical Connections in a Network

Leetcode Solutions

Define a dfs function that takes a node and its discoveryRank.
Build the graph using an adjacency list structure.
Convert the list of connections into a dictionary for efficient edge removal.
Define a rank array to keep track of the rank of nodes.
In the dfs function, assign the discoveryRank to the node if it has not been visited.
Iterate over the node's neighbors, making recursive calls and obtaining recursiveRank.
If recursiveRank is less than discoveryRank, discard the edge as it is part of a cycle.
Record the minimum rank from all neighbors and return it.
Call dfs starting from node 0 with rank 0.
After DFS completes, convert the remaining edges in the dictionary to a list and return as the result.
