A graph is said to be bipartite if we can divide the set of vertices in two disjoint sets such that there is no edge between vertices belonging to same set. Let's break it down. Here we are dividing set of vertices in two groups (or sets). Each vertex goes into one of these groups. This is like labelling each vertex either A or B. how is flexibility used in netball
