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中除法不會返回整數(shù)
    return nums[Math.floor(nums.length / 2)];
};
