Problem Statement

Given integer base $a$ and non-negative integer exponent $b$, compute the power using ** and pow().

Input

One line containing integers $a,b$.

Output

Print $a^b$ using **, then print the value computed by pow(a,b) on the next line.

Subtask

• Subtask 1 — 100 points: $-10\le a\le10$; $0\le b\le10$. Python defines $a^0=1$, including $0^0$.

Example

Input

-2 3

Output

-8
-8

Explanation

With base $-2$ and exponent $3$, the product $(-2)(-2)(-2)$ is $-8$. Both ** and pow() print -8.
