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 $\\text{pow}(6,3)=216$.
