Problem Statement

Write a C program with a function `int isPrime(int n)` that returns 1 if N is prime, else 0.

Input Format

A single integer N.

Output Format

Print 'Prime' if function returns 1, otherwise 'Not Prime'.

Constraints

1 <= N <= 1000000

Sample Input

7

Sample Output

Prime

Explanation

7 is prime, so isPrime returns 1.

Starter Code

#include <stdio.h>

// Define isPrime here

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Check and print
    }
    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
