Description
Given an integer a and a positive integer n, find the power an.

Enter a
line containing two integers a and n. -1000000 <= a <= 1000000, 1 <= n <= 10000.
Output
an integer, which is the result of the power. The title guarantees that the absolute value of the final result does not exceed 1,000,000.
