+<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>&nbsp;</p>
+<p><strong class="example">Example 1:</strong></p>
+
+<pre><strong>Input:</strong> coordinates = "a1"
+<strong>Output:</strong> false
+<strong>Explanation:</strong> From the chessboard above, the square with coordinates "a1" is black, so return false.
+</pre>
+
+<p><strong class="example">Example 2:</strong></p>
+
+<pre><strong>Input:</strong> coordinates = "h3"
+<strong>Output:</strong> true
+<strong>Explanation:</strong> From the chessboard above, the square with coordinates "h3" is white, so return true.
+</pre>
+
+<p><strong class="example">Example 3:</strong></p>
+
+<pre><strong>Input:</strong> coordinates = "c7"
+<strong>Output:</strong> false
+</pre>
+
+<p>&nbsp;</p>
+<p><strong>Constraints:</strong></p>
+
+<ul>
+	<li><code>coordinates.length == 2</code></li>
+	<li><code>'a' &lt;= coordinates[0] &lt;= 'h'</code></li>
+	<li><code>'1' &lt;= coordinates[1] &lt;= '8'</code></li>
