For the hospital assignment problem (Q2 of Thursday July 9 discussion session), assume that the number of people n can be divided by the number of hospitals k, what is INCORRECT about the following statement? a) If there is a flow of 1 on an edge from a person node i to a hospital nodej, it means that person i has been assigned to hospital j.
b) The capacity on each edge from a hospital node to the sink node t should be set as n/k.
c) If the maximum flow of the flow network is n/k, it means that we can assign exactly n/k injured people to each hospital.
d) The capacity from source node s to each person node that represents someone get injured should be set as 1.
