Answer #1

ANSWER:

A maximum flow in this new-built network is the solution to the problem, the sources now become ordinary vertices, and they are subject to the entering-flow equals leaving-flow property.
They must lead to at least O(N³) approach.
If the flow capacities are large numbers, then another algorithm (such as dynamic programming or greedy), is more appropriate.
