JG loves watching war movies! There's a game description with a war. There are two teams, each of many people. There are 3 rounds of fighting, in each round the two teams send some people to fight. In each round, whichever team sends more people wins, and if the two teams send the same amount of people, First team wins. Each person can be sent out to only one round. The team wins 2 rounds win the whole game. Note, the arrangement of the fighter in three rounds must be decided before the whole game starts. We know that there are N people on the First team, and that there are M people on the opposite team. Now jg wants to know whether there exists an arrangement of people for the First team so that they can always win, no matter how the opposite team arrange their people. |
