A special two-digit number is such that when the sum of its digits is added to the product of its digits, the result is equal to the original two-digit number.
Example: Consider the number 59.Sum of digits = 5 + 9 = 14Product of digits = 5 * 9 = 45Sum of the sum of digits and product of digits = 14 + 45 = 59
Write a program to accept a two-digit number. Add the sum of its digits to the product of its digits. If the value is equal to the number input, then display the message "Special two—digit number" otherwise, display the message "Not a special two-digit number".
🚀 Programming Example
A special two-digit number is such that when the sum of its digits is added to the product of its digits, the result is equal to the original two-digit number.
Example: Consider the number 59.
Sum of digits = 5 + 9 = 14
Product of digits = 5 * 9 = 45
Sum of the sum of digits and product of digits = 14 + 45 = 59
Write a program to accept a two-digit number. Add the sum of its digits to the product of its digits. If the value is equal to the number input, then display the message "Special two—digit number" otherwise, display the message "Not a special two-digit number".

}

int digitSum = 0, digitProduct = 1;
// Calculate the sum and product of the digits
while (num != 0) {
int digit = num % 10;
num /= 10;
digitSum += digit;
digitProduct *= digit;
}
// Check if the sum + product equals the original number
if ((digitSum + digitProduct) == orgNum)
System.out.println(orgNum + " is a special 2-digit number");
else
System.out.println(orgNum + " is not a special 2-digit number");
// Close the Scanner to prevent resource leaks
in.close();
}
// Main method - Entry point of the program
public static void main(String[] args) {
// Create an object of the class and call the checkNumber method
RAnsariSpecialNumber specialNumber = new RAnsariSpecialNumber();
specialNumber.checkNumber();
}
}
Enter a 2-digit number: 59
59 is a special 2-digit number
