1812 - Determine Color of a Chessboard Square.<p>Easy</p> <p>You are given <code>coordinates</code>, a string that represents the coordinates of a square of the chessboard. Below is a chessboard for your reference.</p> <p><img src="https://assets.leetcode.com/uploads/2021/02/19/screenshot-2021-02-20-at-22159-pm.png" alt="" /></p> <p>Return <code>true</code> <em>if the square is white, and</em> <code>false</code> <em>if the square is black</em>.</p> <p>The coordinate will always represent a valid chessboard square. The coordinate will always have the letter first, and the number second.</p> <p><strong>Example 1:</strong></p> <p><strong>Input:</strong> coordinates = &ldquo;a1&rdquo;</p> <p><strong>Output:</strong> false</p> <p><strong>Explanation:</strong> From the chessboard above, the square with coordinates &ldquo;a1&rdquo; is black, so return false.</p> <p><strong>Example 2:</strong></p> <p><strong>Input:</strong> coordinates = &ldquo;h3&rdquo;</p> <p><strong>Output:</strong> true</p> <p><strong>Explanation:</strong> From the chessboard above, the square with coordinates &ldquo;h3&rdquo; is white, so return true.</p> <p><strong>Example 3:</strong></p> <p><strong>Input:</strong> coordinates = &ldquo;c7&rdquo;</p> <p><strong>Output:</strong> false</p> <p><strong>Constraints:</strong></p> <ul> <li><code>coordinates.length == 2</code></li> <li><code>'a' <= coordinates[0] <= 'h'</code></li> <li><code>'1' <= coordinates[1] <= '8'</code></li> </ul>
