Bipartite graph

A bipartite graph is like having two groups of friends - group A and group B. In this graph, each friend in group A can only be friends with people in group B, and each friend in group B can only be friends with people in group A. So each friend only has friends in the other group, and there are no friendships within each group. It's like a divide between two groups of people who cannot be friends with each other, but everyone in their group can be friends with everyone in the other group. This concept can be used in many different situations, like matching socks or pairing employees with specific tasks.
