Integer Exponentiation

Given two non-negative integers base and exponent, compute the result of raising the base to the power of the exponent, i.e. \(base^{exponent}\). In particular, note that when both base and exponent are zero, the answer is defined as 1.

Examples:

• Input: 2 3, Output: 8
• Input: 5 0, Output: 1
• Input: 0 3, Output: 0

Your task is to implement this computation. Ensure the program reads input from standard input (stdin) and outputs the answer to standard output (stdout).

inputFormat

The input consists of a single line containing two non-negative integers separated by spaces. The first integer represents the base and the second integer represents the exponent.

outputFormat

Output a single integer: the result of (base^{exponent}) computed according to the rules described, with the special case (0^0 = 1).## sample
