Determine Color of a Chessboard Square
You are given coordinates, a string that represents the coordinates of a square of the chessboard.
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'
