Problem Statement

Write a C program using recursion to calculate base raised to the power exponent ($base^{exponent}$).

Input Format

Two integers: base and exponent.

Output Format

Print the result of base raised to exponent.

Constraints

0 <= base <= 10, 0 <= exponent <= 10

Sample Input

2 3

Sample Output

8

Explanation

Recursive relation: power(base, exp) = base * power(base, exp - 1) with base case exponent 0 returning 1.

Starter Code

#include <stdio.h>

long long power(int base, int exp) {
    // Write your recursive logic here
}

int main() {
    int base, exp;
    if (scanf("%d %d", &base, &exp) == 2) {
        printf("%lldn", power(base, exp));
    }
    return 0;
}

Intermediate

Embedded systems rely on efficient low-level programming to interact directly with hardware. In this course, you will learn how to write practical Embedded C programs used in real microcontroller-based systems. Rather than focusing only on theory, this course follows a practice-driven approach. Each lesson includes hands-on coding exercises that simulate real firmware development tasks used
