Question

02. 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 integer

The web page's width and length you designed must be positive integers.

class Solution {

public:

    vector<int> constructRectangle(int area) {

       

    }

};

Answer 1

class Solution {

public:

vector<int> constructRectangle(int area) {

int height , width;

for (int i = 1; i * i <= area; ++i) {

if (area % i == 0)

width = i;

}

height = area/width;

vector<int> result;

result.push_back(height);

result.push_back(width);

return result;

}

};
