# 这里group by是按每个月来数次数 (select count(distinct requester_id, accepter_id) as c, month(accept_date) from request_accepted group by 2) b; where a.month
Example 2 : Input: 8 Output: 2 Explanation: The square root of 8 is 2.82842..., and since the decimal part is truncated, 2 is returned. 1 2 3 4 2.Answer easy类型题目。。 我的方法1:(逗比解法) AC代码如下: class Solution { public: int mySqrt(int x) { int res = 0; for(long...
Explanation: The binary representation of 1 is 1 (no leading zero bits), and its complement is 0. So you need to output 0. 具体实现 classSolution{public:intfindComplement(intnum){inti =0;while(num >=pow(2, i)) { i++; }intvalue =pow(2, i >0? i :1) -1;returnvalue ^ num;...
You need to output the length L and the width W of the web page you designed in sequence. Example: Input: 4 Output: [2, 2] Explanation: The target area is 4, and all the possible ways to construct it are [1,4], [2,2], [4,1]. ...
