#include <stdio.h>

// Function to check whether a number is an Armstrong number
int isArmstrong(int num) {
    int originalNum, remainder, result = 0, n = 0;

    originalNum = num;

    // Count the number of digits
    while (originalNum != 0) {
        originalNum /= 10;

        result += pow(remainder, n);
        originalNum /= 10;
    }

    // Check if the number is Armstrong
    if (result == num)
