169. Majority Element

题目

Given an array of size n, find the majority element. The majority element is the element that appears more than ⌊ n/2 ⌋ times.

You may assume that the array is non-empty and the majority element always exist in the array.

Example 1:

Input: [3,2,3]
Output: 3

Example 2:

Input: [2,2,1,1,1,2,2]
Output: 2

题目大意

给定一个大小为 n 的数组,找到其中的众数。众数是指在数组中出现次数大于 ⌊ n/2 ⌋ 的元素。你可以假设数组是非空的,并且给定的数组总是存在众数。
