Why there is no new contest upcoming on code forces?? It just felt kind of weird that there is no new contest coming. When will there be a new contest ?? Any ideas
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.
