+ * 492. Construct the Rectangle
+ * https://leetcode.com/problems/construct-the-rectangle/
+ * Difficulty: Easy
+ *
+ * A web developer needs 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:
+ *
+ * The area of the rectangular web page you designed must equal to the given
+ * target area. The width W should not be larger than the length L, which
+ * means L >= W. The difference between length L and width W should be as
+ * small as possible.
+ *
+ * Return an array [L, W] where L and W are the length and width of the web
+ * page you designed in sequence.
