Problem Statement

Write a C program to check if a number is Armstrong using a helper cube function `int cube(int n)`.

Input Format

A 3-digit integer N.

Output Format

Print 'Armstrong' or 'Not Armstrong'.

Constraints

100 <= N <= 999

Sample Input

Sample Output

Armstrong

Explanation

Uses modular decomposition with a separate cube function.

Starter Code

#include <stdio.h>

// Define cube function here

int main() {
    int n;
    if (scanf("%d", &n) == 1) {
        // Check Armstrong and print
    }
    return 0;
}
