    2660 - Determine the Winner of a Bowling Game.

    Easy

    You are given two 0-indexed integer arrays player1 and player2, that represent the number of pins that player 1 and player 2 hit in a bowling game, respectively.

    The bowling game consists of n turns, and the number of pins in each turn is exactly 10.

    Assume a player hit xi pins in the ith turn. The value of the ith turn for the player is:

    • 2xi if the player hit 10 pins in any of the previous two turns.
    • Otherwise, It is xi.

    The score of the player is the sum of the values of their n turns.

    Return

    • 1 if the score of player 1 is more than the score of player 2,
    • 2 if the score of player 2 is more than the score of player 1, and
    • 0 in case of a draw.

    Example 1:

    Input: player1 = [4,10,7,9], player2 = [6,5,2,3]

    Output: 1

    Explanation: The score of player1 is 4 + 10 + 27 + 29 = 46.

    The score of player2 is 6 + 5 + 2 + 3 = 16.

    Score of player1 is more than the score of player2, so, player1 is the winner, and the answer is 1.

    Example 2:

    Input: player1 = [3,5,7,6], player2 = [8,10,10,2]

    Output: 2

    Explanation: The score of player1 is 3 + 5 + 7 + 6 = 21.

    The score of player2 is 8 + 10 + 210 + 22 = 42.

    Score of player2 is more than the score of player1, so, player2 is the winner, and the answer is 2.

    Example 3:

    Input: player1 = [2,3], player2 = [4,1]

    Output: 0

    Explanation: The score of player1 is 2 + 3 = 5

    The score of player2 is 4 + 1 = 5

    The score of player1 equals to the score of player2, so, there is a draw, and the answer is 0.

    Constraints:

    • n == player1.length == player2.length
    • 1 <= n <= 1000
    • 0 <= player1[i], player2[i] <= 10
