1209. 构造矩形(经典)

class Solution:
    """
    @param area: web page’s area
    @return: the length L and the width W of the web page you designed in sequence
    """
    ‘‘‘ 
    大致思路:
    1.首先从中间开始求平方根，然后判断area%开始数 == 0,如果是等于0的话，则返回，否则开始数 - 1，继续找，最终返回.
    ‘‘‘
    def constructRectangle(self,area):
        l = int(math.sqrt(area))
        while  area%l != 0:
            l -= 1
        return [area//l,l]
