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:

  1. The given area won‘t exceed 10,000,000 and is a positive integer
  2. The web page‘s width and length you designed must be positive integers. 
给定矩形的面积area，返回矩形的长度L和宽度W，使得L和W的差值最小。
  1. public class Solution {
  2.     public int[] ConstructRectangle(int area) {
  3. 		if (area == 0) {
  4. 			int[] arr = { };
  5. 			return arr;
  6. 		}
  7. 		int[] result = { area, 1 };
  8. 		for(int height = 1; height <= area; height++) {
  9. 			if (area % height == 0) {
  10. 				int width = area / height;
  11. 				if (width < height) {
  12. 					break;
  13. 				}else if (width - height < result[0] - result[1]) {
  14. 					result[0] = width;
  15. 					result[1] = height;
  16. 				}
  17. 			}
  18. 		}
  20. 		return result;
  21.     }
  22. }
