WebThe find_odd_cycle function tests a given graph for bipartiteness using a DFS-based coloring approach. An undirected graph is bipartite if one can partition its set of vertices into two sets "left" and "right", such that each edge goes from either side to the other. Obviously, a two-coloring of the graph is exactly the same as a two-partition. WebA graph is said to be bipartite if it can be divided into two independent sets A and B such that each edge connects a vertex from A to B.It is obvious that if a graph has an odd …
