*
* wap to accept a number and check it is special number or not.
* A number is said to be special if the sum of the factorial of its digits is equal to the number itself.
* example 145.
* 1!+4!+5!=145
* 1+24+120=145
*
* using a function int fact(int n)- accepts a number and returns its factorial

HEY BUDDY HERE IS UR ANSWER

Explanation:

import java.util.*;

public class JavaHungry

{

   

   public static void main(String args[])

{

       System.out.println("Enter any number : ");

       Scanner scan = new Scanner(System.in);

       int inputNumber = scan.nextInt();

       boolean result = specialnumber(inputNumber);

       if (result == true)

           System.out.println(inputNumber + " is a Special number");

       if (result == false)

           System.out.println(inputNumber + " is NOT a Special number");        

   }

   

   public static boolean specialnumber(int inputNumber)

{  

 

       // Create a copy of the inputNumber  

       int temp = inputNumber;

 

       // Initialize sumOfDigits of inputNumber

       int sumOfDigits = 0;  

 

       /* Calculate the sum of factorial of

          digits */  

       while (temp != 0) {  

          // Get the rightmost digit  

           int currentDigit = temp % 10;

           sumOfDigits = sumOfDigits + factorial(currentDigit);

           temp = temp/10;

       }  

       /* If sumOfDigits is equal to inputNumber then  

       the number is Special, otherwise not */  

       return (sumOfDigits == inputNumber);

   }

   

   public static int factorial(int number) {

       if (number == 1 || number == 0)

           return 1;

       else  

           return (number * factorial(number -1));

   }

}
