Algorithms

You are given two strings, <code>coordinate1</code> and <code>coordinate2</code>, representing the coordinates of a square on an <code>8 x 8</code> chessboard.

Below is the chessboard for reference.

<img alt="" src="https://assets.leetcode.com/uploads/2024/07/17/screenshot-2021-02-20-at-22159-pm.png" style="width: 400px; height: 396px;" />

Return <code>true</code> if these two squares have the same color and <code>false</code> otherwise.

The coordinate will always represent a valid chessboard square. The coordinate will always have the letter first (indicating its column), and the number second (indicating its row).

&nbsp;
Example 1:

<div class="example-block">
Input: coordinate1 = &quot;a1&quot;, coordinate2 = &quot;c3&quot;

Output: true

Explanation:

Both squares are black.
</div>

Example 2:

<div class="example-block">
Input: coordinate1 = &quot;a1&quot;, coordinate2 = &quot;h3&quot;

Output: false

Explanation:

Square <code>&quot;a1&quot;</code> is black and <code>&quot;h3&quot;</code> is white.
</div>

&nbsp;
Constraints:

<ul>
	<li><code>coordinate1.length == coordinate2.length == 2</code></li>
	<li><code>&#39;a&#39; &lt;= coordinate1[0], coordinate2[0] &lt;= &#39;h&#39;</code></li>
	<li><code>&#39;1&#39; &lt;= coordinate1[1], coordinate2[1] &lt;= &#39;8&#39;</code></li>
</ul>

判断国际象棋棋盘中一个格子的颜色

Math

String

给你两个字符串 <code>coordinate1</code> 和 <code>coordinate2</code>，代表 <code>8 x 8</code> 国际象棋棋盘上的两个方格的坐标。

以下是棋盘的参考图。

<img alt="" src="https://assets.leetcode.com/uploads/2024/07/17/screenshot-2021-02-20-at-22159-pm.png" style="width: 400px; height: 396px;" />

如果这两个方格颜色相同，返回 <code>true</code>，否则返回 <code>false</code>。

坐标总是表示有效的棋盘方格。坐标的格式总是先字母（表示列），再数字（表示行）。

&nbsp;

示例 1：

<div class="example-block">
输入： coordinate1 = "a1", coordinate2 = "c3"

输出： true

解释：

两个方格均为黑色。
</div>

示例 2：

<div class="example-block">
输入： coordinate1 = "a1", coordinate2 = "h3"

输出： false

解释：

方格 <code>"a1"</code> 是黑色，而 <code>"h3"</code> 是白色。
</div>

&nbsp;

提示：

<ul>
	<li><code>coordinate1.length == coordinate2.length == 2</code></li>
	<li><code>'a' &lt;= coordinate1[0], coordinate2[0] &lt;= 'h'</code></li>
	<li><code>'1' &lt;= coordinate1[1], coordinate2[1] &lt;= '8'</code></li>
</ul>
