Rock, Paper, Airstrike
By Jeremias Gomes, Universidade de Brasília 
Brazil
Timelimit: 1
Rock, Paper, Airstrike is a very popular children’s game, in which two or more children form a circle and do hand gestures in an attempt to get the victory. The rules are surprisingly complex for a children’s game, but it’s still quite popular around the world.
The games are very simple. Players can choose between the sign of a Rock (fist), the sign of a paper (an open palm), and the signal to the Air Attack (like the paper, but with only the thumb and little finger extended).
A game with two players have the following rules to determine a winner:
- Airstrike vs. Rock: In this case, the player with Airstrike defeats the player with Rock for obvious reasons.
- Rock vs. Paper: In this case the player with Rock defeats the one with Paper, because Rock hurts more.
- Paper vs. Airstrike: In here Airstrike wins because Airstrike always wins and Paper is pathetic.
- Paper vs. Paper: In this variation both players win because Paper is useless and no one facing Paper can lose.
- Rock vs. Rock: To this case there is no winner because it depends on what the players decide to do with the Rock and usually do nothing at the end.
- Airstrike vs. Airstrike: When this happens all players lose due to Mutual Annihilation.
Your task is to write a program that given the choice of two players tell who won the game.
Input
The input consist of N (1 ≤ N ≤ 1000) test cases. N should be read in the first line of input. Each test case is composed of two lines each containing a string. The first string is the sign chosen by Player 1 and the second string is the sign chosen by the Player 2. These string can be:
- “ataque”: to represents Airstrike
- “pedra”: to represents Rock
- “papel”: tp represents Paper
Output
The output must be contain:
- “Jogador 1 venceu”: if Player 1 has won the game
- “Jogador 2 venceu”: if Player 2 has won the game
- “Ambos venceram”: if the both have won the game
- “Sem ganhador”: if there is no winner
- “Aniquilacao mutua”: if Mutual Annihilation occurs
Each output of a test case must be in one line.
