 It should be noted that this does not work correctly if multiple edges are present in the graph, as it actually ignores their presence. Of course, multiple edges must not be a part of the answer, so checks must be made in the function $IS$_$BRIDGE$. Another way to work with multiple edges more accurately is to transfer the number of edges by which we entered the current node(we all need to store this additionally).
