leetcode 2和c leetcode-日常记录准备每天不leetcode这个leetcode并用markdown文档做个简单的记录。简单的2021-06-03星期四1365.比当前数小的数有多少。

C++：


class Solution {

public:

    vector<int> smallerNumbersThanCurrent(vector<int>& nums) {

        vector<int> res;

        for (int i = 0; i < nums.size(); i++)

            res.push_back(compare_nums(nums, nums[i]));

        return res;

    }



    int compare_nums(vector<int>& nums, int temp) {

        int res = 0;

        for (int i = 0; i < nums.size(); i++)

            if (nums[i] < temp)

                res++;

        return res;

    }

};

</int></int></int></int>

Python ：


class Solution:

    def smallerNumbersThanCurrent(self, nums):

        return [sum(j < i for j in nums) for i in nums]
