Hanzo Waiting

Wookje is one win away from promotion to Grandmaster, and he has just seen something terrible: his teammates have started throwing the game.

Just as he is about to give up on the promotion, Wookje notices that the enemy team is throwing too! Now nobody can tell how the match will end.

Each team has $N$ players, and every player picks one hero before the game starts. Two players on the same team cannot pick the same hero. The game has a huge number of heroes, and $M$ of them are so bad that picking one decides the outcome of the game. Picking such a hero is called a troll pick. (Both teams play the same game, so the number of troll picks $M$ is the same for both teams.)

Since both teams are throwing, everyone decides to just have fun. Each player names the troll picks they want out of the $M$ troll picks, and each team assigns troll picks so that as many of its players as possible get one. A player who gets no troll pick has to settle for a healer.

The game matches players of similar skill, so the team with fewer troll picks wins. Given the troll picks each player on each team wants, determine whether Wookje reaches Grandmaster. A draw gives no points, so it does not count as a promotion. Of course, Wookje is throwing too.

The first line contains the number of players on one team $N$ ($1 \le N \le 300$), the number of troll picks $M$ ($1 \le M \le 300$), and the numbers of wish entries of the two teams $K_1$ and $K_2$ ($1 \le K_1, K_2 \le 500$).

Each of the next $K_1$ lines contains two integers $i$ and $j$ ($1 \le i \le N$, $1 \le j \le M$), meaning that player $i$ on Wookje's team wants troll pick $j$.

The next $K_2$ lines give the troll picks wanted by the players on the enemy team in the same format.
