Two players play a game with dice. The results are stored in `diceRolls`, a list of pairs where each pair `(A, B)` represents a roll: `A` is Player 1's roll and `B` is Player 2's roll. A player gets 1 point if their roll is higher than the other's. If both roll the same, no one gets a point. The procedure `getWinner` should return `1` if Player 1 wins, `2` if Player 2 wins, and `0` for a tie. Which procedure(s) is/are correct?
