\end{figure} The bipartite graph in Fig. 2 shows the possible allocations of people \(A , B , C , D , E\) and \(F\) to tasks \(1,2,3,4,5\) and 6. An initial matching is obtained by matching the following pairs \(A\) to \(3 , \quad B\) to \(4 , \quad C\) to \(1 , \quad F\) to 5 .
  1. Show this matching in a distinctive way on the diagram in the answer book.
  2. Use an appropriate algorithm to find a maximal matching. You should state any alternating paths you have used.
