Consider the two circulation networks G1 and G2 shown below. For each of the two networks, state whether there exists a circulation or not. If there exists a circulation, show the circulation flow of each edge, obtained by finding the max flow value from the flow network constructed from the circulation network (show the constructed flow network as well). If there exists no circulation, show a cut that violates the condition _vB d_v c(A,B)
