Power of a Number using Recursion
Detailed guide and Python implementation for the 'Power of a Number using Recursion' problem.
Problem Statement
Write a function power(base, exp) that computes base raised to the power exp using recursion. The function should take two integers base and exp as input and return the result as an integer. Assume exp is always non-negative.
- •0 <= exp <= 20
- •-10 <= base <= 10
Examples
base = 2, exp = 10
1024
2^10 = 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 * 2 = 1024
base = 3, exp = 4
81
3^4 = 3 * 3 * 3 * 3 = 81
base = 5, exp = 0
1
Any number raised to the power 0 is 1
