Write a Java program to input a number. Calculate and display the factorial of each digit.
Sample Input: 365
Sample Output:
Factorial of 5 = 120
Factorial of 6 = 720
Factorial of 3 = 6
Answer
import java.util.Scanner;
public class KboatDigitFactorial
{
public static void main(String args[]) {
Scanner in = new Scanner(System.in);
System.out.print("Enter number: ");
int n = in.nextInt();
while (n != 0) {
int d = n % 10;
n /= 10;
int f = 1;
for (int i = 1; i <= d; i++) {
f *= i;
}
System.out.println("Factorial of " + d + " = " + f);
}
}
}Output

Define a class to accept a number and check whether it is a SUPERSPY number or not. A number is called SUPERSPY if the sum of the digits equals the number of the digits.
Example1:
Input: 1021 output: SUPERSPY number [SUM OF THE DIGITS = 1+0+2+1 = 4, NUMBER OF DIGITS = 4 ]Example2:
Input: 125 output: Not an SUPERSPY number [1+2+5 is not equal to 3]Rewrite the following do while program segment using for:
