LeetCode题解：Construct the Rectangle

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.

题解：

std::vector<int> constructRectangle(int area) {
int square_root = std::sqrt(area);
for(int i = square_root; i > 0; --i) {
if (area % i == 0) {
return std::vector<int>{area / i, i};
}
}
return std::vector<int>{area, 1};
}
