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.

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 =.

Constraints

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

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