Power of a Number

Given two integers base and exponent, return base raised to the power of exponent.

Example 1:

Input: base = 2, exponent = 3
Output: 8
Explanation: 2^3 = 2 × 2 × 2 = 8

Example 2:

Input: base = 5, exponent = 0
Output: 1
Explanation: Any number to the power of 0 is 1

Constraints:

• -10 <= base <= 10
• 0 <= exponent <= 10
