Implement boar$\_$brawl, which takes the player's current score player$\_$score and the opponent's current score opponent$\_$score, and returns the number of points scored by Boar Brawl when the player rolls $0$ dice.

Boar Brawl. A player who rolls zero dice scores three times the absolute difference between the tens digit of the opponent$$s score and the ones digit of the current player$$s score, or $1,$ whichever is higher. The ones digit refers to the rightmost digit and the tens digit refers to the second$-$rightmost digit. If a player's score is a single digit $($less than $10),$ the tens digit of that player's score is $0.$
