Description

The National Intelligence Council of Nation X receives a piece of credible information that Nation Y will send spies to steal Nation X’s confidential paper. So the commander of The National Intelligence Council take measures immediately.

He will investigate people who will come into Nation X. At the same time, there are two List in the Commander’s hand, one is full of spies that Nation Y will send to Nation X, and the other one is full of spies that Nation X has sent to Nation Y before. There may be some overlaps of the two list. Because the spy may act two roles at the same time, which means that he may be the one that is sent from Nation X to Nation Y, we just call this type a “dual-spy”. So Nation Y may send “dual_spy” back to Nation X, and it is obvious now that it is good for Nation X, because “dual_spy” may bring back Nation Y’s confidential paper without worrying to be detention by Nation Y’s frontier. So the commander decides to seize those that are sent by Nation Y, and let the ordinary people and the “dual_spy” in at the same time .So can you decide a list that should be caught by the Commander?
