Check wether the graph is bipartite after adding each edge
Given multiple inputs of the edges in a graph such as(first line being number of connections):
4 1 2 2 3 5 6 1 5
I have to check that after each input whether the graph remains bipartite or not, we will just break if graph is non-bipartite. I think this is some graph coloring problem but I am unable to implement it, please help me by providing some algorithm to do so.
