在给出x和y的x ^(y ^ 2)或y ^(x ^ 2)中找到最大值

给定X和Y的值大于2，任务是找出其中最大的X和Y

x^(y^2) and y^(x^2)

考虑x大于y或y大于x 。因此，如果x ^(y ^ 2)较大，则打印1；如果y ^(x ^ 2)较大，则打印2 。

例子：

Input: X = 4, Y = 9
Output: 1

Input: X = 4, Y = 3
Output: 2

方法：假设$x^y^2 > y^x^2$ ，然后在两边取ln并除以$(xy)^2$我们可以得到$ln(x)/(x^2) > ln(y)/(y^2)$ 。

拿$F(x) = ln(x)/(x^2)$ 。该函数单调递减$x > 2$ 。

If x > y, then F(x) < F(y)
