<p>给定一个大小为 <code>n</code><em> </em>的数组 <code>nums</code> ,返回其中的多数元素。多数元素是指在数组中出现次数 <strong>大于</strong> <code>⌊ n/2 ⌋</code> 的元素。</p>
 | 
						||
 | 
						||
<p>你可以假设数组是非空的,并且给定的数组总是存在多数元素。</p>
 | 
						||
 | 
						||
<p> </p>
 | 
						||
 | 
						||
<p><strong>示例 1:</strong></p>
 | 
						||
 | 
						||
<pre>
 | 
						||
<strong>输入:</strong>nums = [3,2,3]
 | 
						||
<strong>输出:</strong>3</pre>
 | 
						||
 | 
						||
<p><strong>示例 2:</strong></p>
 | 
						||
 | 
						||
<pre>
 | 
						||
<strong>输入:</strong>nums = [2,2,1,1,1,2,2]
 | 
						||
<strong>输出:</strong>2
 | 
						||
</pre>
 | 
						||
 | 
						||
<p> </p>
 | 
						||
<strong>提示:</strong>
 | 
						||
 | 
						||
<ul>
 | 
						||
	<li><code>n == nums.length</code></li>
 | 
						||
	<li><code>1 <= n <= 5 * 10<sup>4</sup></code></li>
 | 
						||
	<li><code>-10<sup>9</sup> <= nums[i] <= 10<sup>9</sup></code></li>
 | 
						||
</ul>
 | 
						||
 | 
						||
<p> </p>
 |

<p><strong>进阶:</strong>尝试设计时间复杂度为 O(n)、空间复杂度为 O(1) 的算法解决此问题。</p>
