Power ⭐⭐

Read two integers: base and exponent. Compute base^exponent using a for loop.

What is a power?

A power base^exponent means multiplying the base by itself exponent times.

• 2^3 = 2 * 2 * 2 = 8
• 5^1 = 5
• 7^0 = 1

In this exercise, assume exponent is greater than or equal to 0.

Input

Two integers:

1. base
2. exponent

Output

Print a single number: the value of base^exponent.

Example

Input:

2 5

Output:

32
