1812. Determine Color of a Chessboard Square Easy

1/**
2 * [1812] Determine Color of a Chessboard Square
3 *
4 * You are given coordinates, a string that represents the coordinates of a square of the chessboard. Below is a chessboard for your reference.
5 * <img alt="" src="https://assets.leetcode.com/uploads/2021/02/19/screenshot-2021-02-20-at-22159-pm.png" style="width: 400px; height: 396px;" />
6 * Return true if the square is white, and false if the square is black.
7 * The coordinate will always represent a valid chessboard square. The coordinate will always have the letter first, and the number second.
8 *  
9 * Example 1:
10 * 
11 * Input: coordinates = "a1"
12 * Output: false
13 * Explanation: From the chessboard above, the square with coordinates "a1" is black, so return false.
14 * 
15 * Example 2:
16 * 
17 * Input: coordinates = "h3"
18 * Output: true
19 * Explanation: From the chessboard above, the square with coordinates "h3" is white, so return true.
20 * 
21 * Example 3:
22 * 
23 * Input: coordinates = "c7"
24 * Output: false
25 * 
26 *  
27 * Constraints:
28 * 
29 * 	coordinates.length == 2
30 * 	'a' <= coordinates[0] <= 'h'
31 * 	'1' <= coordinates[1] <= '8'
32 *
