This can be easily solved with Bridge Tree.

    What about pair of nodes that are in same BCC? (One needs Min Cut for that I guess)

      They are not disconnected by definition

        I guess I misunderstood the problem. I thought it was asking about minimum number of edges such that removing them will disconnect two given nodes. Which is basically min-cut in BCC.
        Any idea how to solve that? ^

          It’s min cut by definition, given that answer >= 2
