leetcode169Majority 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.

这个题目很简单，，，排序一下，遍历统计一下最出现次数最多，保存下来，即可。

class Solution {
public:
    int majorityElement(vector<int>& nums) {
        sort(nums.begin(), nums.end());
        int maxv = nums[0], maxvc = nums[0], maxc = 0, count = 0;
        for (vector<int>::iterator it = nums.begin(); it != nums.end(); ++it)
        {
            if (maxvc != *it)
            {
                if (count > maxc)
                {
                    maxv = maxvc;
                    maxc = count;
                }
                maxvc = *it;
                count = 0;
            }
            count++;
        }
    	if (count > maxc)
	    {
    		maxv = maxvc;
    		maxc = count;
	    }
        
        return maxv;
    }
};
