code: # A Bipartite Graph is a graph whose vertices can be divided into two independent sets,
  # U and V such that every edge (u, v) either connects a vertex from U to V or a vertex
  # from V to U. In other words, for every edge (u, v), either u belongs to U and v to V,
  # or u belongs to V and v to U. We can also say that there is no edge that connects
  # vertices of same set.
