问题描述

对于一个基数 $X$，将它连乘 $Y$ 次得到的积被称为 $X$ 的 $Y$ 次幂，并表示为 $\text{pow}(X, Y)$。例如，我们有 $\text{pow}(2,3)=2\times 2\times 2=8$。

给定三个整数 $A$、$B$ 和 $C$，比较 $\text{pow}(A,C)$ 和 $\text{pow}(B,C)$，以确定哪一个较大。

以上为通义千问 qwen-max 翻译，仅供参考。

Problem Statement

For a base number $X$, the product of multiplying it $Y$ times is called $X$ to the $Y$-th power and represented as $\text{pow}(X, Y)$. For example, we have $\text{pow}(2,3)=2\times 2\times 2=8$.

Given three integers $A$, $B$, and $C$, compare $\text{pow}(A,C)$ and $\text{pow}(B,C)$ to determine which is greater.

Constraints

• $-10^9 \leq A,B \leq 10^9$
• $1 \leq C \leq 10^9$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$A$ $B$ $C$

Output

If $\text{pow}(A,C)< \text{pow}(B,C)$, print <; if $\text{pow}(A,C)>\text{pow}(B,C)$, print >; if $\text{pow}(A,C)=\text{pow}(B,C)$, print =.

Sample Input 1

3 2 4

Sample Output 1

\>

We have $\text{pow}(3,4)=81$ and $\text{pow}(2,4)=16$.

Sample Input 2

-7 7 2

Sample Output 2

\=

We have $\text{pow}(-7,2)=49$ and $\text{pow}(7,2)=49$.

Sample Input 3

-8 6 3

Sample Output 3

<

We have $\text{pow}(-8,3)=-512$ and $\text{pow}(6,3)=216$.
