const QUESTIONS = { 1192: { question: (
There are n servers numbered from 0 to{" "}
n - 1 connected by undirected server-to-server{" "}
connections forming a network where{" "}
connections[i] = [ai, bi]
{" "}
represents a connection between servers{" "}
ai
{" "}
and{" "}
bi
. Any server can reach other servers directly or indirectly through
the network.
A critical connection is a connection that, if removed, will make some servers unable to reach some other server.
Return all critical connections in the network in any order.
Example 1:
Input: n = 4, connections = [[0,1],[1,2],[2,0],[1,3]]{" "}
Output: [[1,3]]
Explanation: [[3,1]] is also accepted.
Example 2:
Input: n = 2, connections = [[0,1]]
Output: [[0,1]]
Constraints:
2 <= n <= 105
n - 1 <= connections.length <= 105
0 <= ai, bi <= n - 1
ai != bi
