For a web developer, it is very important to know how to design a web page's size. So, given a specific rectangular web page’s area, your job by now is to design a rectangular web page, whose length L and width W satisfy the following requirements:
1. The area of the rectangular web page you designed must equal to the given target area. 2. The width W should not be larger than the length L, which means L >= W. 3. The difference between length L and width W should be as small as possible. 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]. But according to requirement 2, [1,4] is illegal; according to requirement 3, [4,1] is not optimal compared to [2,2]. So the length L is 2, and the width W is 2.
Note:
The given area won't exceed 10,000,000 and is a positive integerThe web page's width and length you designed must be positive integers.

给定面积，求最整型长宽大小最接近的一组数据。
思想：对面积直接开方然后根据需求进行加减。
代码如下：
class Solution { public: vector<int> constructRectangle(int area) { vector<int> result(2, 0); int l = sqrt(area), w = sqrt(area); while(l * w != area) { if(l * w < area) l++; else w--; } result[0] = l; result[1] = w; return result; } };
