<p>给定一个只包含整数的有序数组 <code>nums</code>&nbsp;,每个元素都会出现两次,唯有一个数只会出现一次,请找出这个唯一的数字。</p>
<p>&nbsp;</p>
<p><strong>示例 1:</strong></p>
<pre>
<strong>输入:</strong> nums = [1,1,2,3,3,4,4,8,8]
<strong>输出:</strong> 2
</pre>
<p><strong>示例 2:</strong></p>
<pre>
<strong>输入:</strong> nums = [3,3,7,7,10,11,11]
<strong>输出:</strong> 10
</pre>

<ul>
<li><code>1 &lt;= nums.length &lt;= 10<sup>5</sup></code></li>
<li><code>0 &lt;= nums[i]&nbsp;&lt;= 10<sup>5</sup></code></li>
</ul>
<p>&nbsp;</p>
<p><strong>进阶:</strong>&nbsp;采用的方案可以在 <code>O(log n)</code> 时间复杂度和 <code>O(1)</code> 空间复杂度中运行吗?</p>
