169. Majority Element

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.

class Solution(object):
    def majorityElement(self, nums):
        """
        :type nums: List[int]
        :rtype: int
        """
        nums.sort()
        return nums[len(nums)/2]

先排序，因为题目说了这个大多数一定存在 那么这个数一定在中间位置上，用心体会，感觉很巧妙！
