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'
