Day of the Week

Math

给你一个日期，请你设计一个算法来判断它是对应一周中的哪一天。

输入为三个整数：<code>day</code>、<code>month</code> 和&nbsp;<code>year</code>，分别表示日、月、年。

您返回的结果必须是这几个值中的一个&nbsp;<code>{&quot;Sunday&quot;, &quot;Monday&quot;, &quot;Tuesday&quot;, &quot;Wednesday&quot;, &quot;Thursday&quot;, &quot;Friday&quot;, &quot;Saturday&quot;}</code>。

&nbsp;

示例 1：

<pre>输入：day = 31, month = 8, year = 2019
输出：&quot;Saturday&quot;
</pre>

示例 2：

<pre>输入：day = 18, month = 7, year = 1999
输出：&quot;Sunday&quot;
</pre>

示例 3：
