    1812 - Determine Color of a Chessboard Square.

    Easy

    You are given coordinates, a string that represents the coordinates of a square of the chessboard. Below is a chessboard for your reference.

    Return true if the square is white, and false if the square is black.

    The coordinate will always represent a valid chessboard square. The coordinate will always have the letter first, and the number second.

    Example 1:

    Input: coordinates = “a1”

    Output: false

    Explanation: From the chessboard above, the square with coordinates “a1” is black, so return false.

    Example 2:

    Input: coordinates = “h3”

    Output: true

    Explanation: From the chessboard above, the square with coordinates “h3” is white, so return true.

    Example 3:

    Input: coordinates = “c7”

    Output: false

    Constraints:

    • coordinates.length == 2
    • 'a' <= coordinates[0] <= 'h'
    • '1' <= coordinates[1] <= '8'
