  1. Draw a bipartite graph representing the following adjacency matrix.
    123456
    \(\boldsymbol { A }\)101010
    B010100
    \(\boldsymbol { C }\)010001
    \(\boldsymbol { D }\)000100
    E001011
    \(\boldsymbol { F }\)000110
  2. Initially, \(A\) is matched to \(3 , B\) is matched to \(4 , C\) is matched to 2 , and \(E\) is matched to 5 . Use the maximum matching algorithm, from this initial matching, to find a complete matching. List your complete matching.
