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'`
