// 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.
// Example 1:
// Input: area = 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.
// Example 2:
// Input: area = 37
// Output: [37,1]
// Example 3:
// Input: area = 122122
// Output: [427,286]
// Constraints:
// 1 <= area <= 107
