WebSep 28, 2024 · Bridges in a graph. Given an undirected Graph, The task is to find the Bridges in this Graph. An edge in an undirected connected graph is a bridge if removing it disconnects the graph. For a disconnected undirected graph, definition is similar, a bridge is an edge removing which increases number of disconnected components.
