Special Number

PROGRAM : SPECIAL NUMBER

 Check whether a number is Special Number in JAVA. This program checks whether a number is a Special Number or not. A number is said to be special number when the sum of factorial of its digits is equal to the number itself. Example- 145 is a Special Number as 1!+4!+5!=145

 SYNTAX:

 import java.io.*;
class special_number
{
    public static void main(String args[])throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.println("Enter a number");
        int n=Integer.parseInt(br.readLine());
        int n1=n;int d=0,sum=0,f=1;
        while(n!=0)
        {f=1;
            d=n%10;
            for(int i=1;i<=d;i++)
            {f*=i;
            }
            sum+=f;
            n=n/10;
        }
        if(sum==n1)
        System.out.println("YES THE NUMBER IS  SPECIAL NUMBER");
        else
        System.out.println("NO THE  NUMBER IS NOT SPECIAL NUMBER");
    }
}

Arranging according to potential.

PROGRAM: Requested by Sir  Ankur Acharya   ARRANGING WORDS IN A STRING ACCORDING TO THEIR POTENTIAL The encryption of alphabets are to be done as follows: A = 1 B = 2 C = 3 . . . Z = 26 The potential of a word is found by adding the encrypted value of the alphabets. Example: KITE Potential = 11 + 9 + 20 + 5 = 45 Accept a sentence which is terminated by either “ . ” , “ ? ” or “ ! ”. Each word of sentence is separated by single space. Decode the words according to their potential and arrange them in ascending order. Output the result in format given below: Example 1 INPUT : THE SKY IS THE LIMIT. POTENTIAL : THE = 33 SKY = 55 IS = 28 THE = 33 LIMIT = 63 OUTPUT : IS THE THE SKY LIMIT Example 2 INPUT : LOOK BEFORE YOU LEAP. POTENTIAL : LOOK = 53 BEFORE = 51 YOU = 61 LEAP = 34 OUTPUT : LEAP BEFORE LOOK YOU SYNTAX import java.io.*; class Potential {     public static void main(String args[])throws IOException     {       ...

Disarium Number

AJ Java Programs Program 4: Disarium Number A number will be called DISARIUM if sum of its digits powered with their respective position is equal to the original number. For example  135 is a DISARIUM (Workings 1 1 +3 2 +5 3  = 135, some other  DISARIUM  are 89, 175, 518 etc) Syntax: import java.io.*; class disarium {     public static void main(String args[])throws IOException     {         BufferedReader br=new BufferedReader(new InputStreamReader(System.in));         int n,n1,n2,c=0,sum=0,d=0;         System.out.println("Enter a Num");         n=Integer.parseInt(br.readLine());         n2=n1=n;         while(n2!=0)         {             n2=n2/10;             c++;         }       ...

SMITH NUMBER

PROGRAM: SMITH NUMBER A   Smith number  is a composite number, the sum of whose digits is the sum of the digits of its prime factors obtained as a result of prime factorization (excluding 1). The first few such numbers are 4, 22, 58, 85, 94, 121 ……………….. For Example 58=> 5+8=13 2+(2+9) of 29 =13 Since sum of digits=sum of digits of prime factors 58 is a SMITH NUMBER SYNTAX: import java.io.*; class smith_no { static int sum,sum1;     public static void main(String args[])throws IOException     {         BufferedReader br=new BufferedReader(new InputStreamReader(System.in));         int n;int c=0;         System.out.println("Enter a Number");         n=Integer.parseInt(br.readLine());         int n1=n;         while(n1!=0){         int d=n1%10;         sum1+=d; ...
