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
/**
* @param {number[]} nums
* @return {number}
*/
var majorityElement = function(nums) {
nums.sort();
// return nums[nums.length / 2]; //JavaScript中除法不会返回整数
return nums[Math.floor(nums.length / 2)];
};
