Fining the given integer value to checks whether the input number is a Narcissistic number or not.

Hi All,


Explanation

First of all, what is a Narcissistic Number?
An n-digit number that is the sum of the nth powers of its digits is called an n-narcissistic number.

For example, take the number 8208

8208 = 8^4 + 2^4 + 0^4 + 8^4

Example:
 8^4 = 8*8*8*8 = 4096
 2^4 = 2*2*2*2 =   16
 0^4 = 0*0*0*0 =    0
 8^4 = 8*8*8*8 = 4096

 Total = 8208

So, this is a Narcissistic Number.


Coding:

import java.io.*;
import java.util.*;
public class MyCode {
    public static void main(String args[] ) throws Exception {

    //Write code here
        Scanner sc =new Scanner(System.in);
        int n= sc.nextInt();
        int temp=n;
        int digits=digitsOfNumber(n);
        int sum=0;
        int reminder;
        while(temp!=0)
        {
            reminder = temp%10;
            sum=sum+(int)Math.pow(reminder,digits);
            temp=temp/10;
        }
        if(sum==n)
            System.out.println("True");
        else
            System.out.println("False");
     
   }
   public static int digitsOfNumber(int n)
   {
        int temp=n;
        int digits=0;
        while(temp!=0)
        {
            digits++;
            temp=temp/10;
        }
        return digits;
    }
}


INPUT
8208
