1812. Determine Color of a Chessboard Square
https://leetcode.com/problems/determine-color-of-a-chessboard-square
Description
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'
