Disarium Number.

-

Program to check whether a given number is Disarium or not.


A number will be called Disarium if sum of its digits powered with their respective postion is equal to the original number.

eg. 135 is a Disarium number because 135 = (1)+(3*3)+(5*5*5) similarly 89, 175, 518 etc are Disarium number






SOURCE CODE

import java.io.*;
public class Disarium
{
    public static void main(String args[])throws IOException
    {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        System.out.print("Enter a Number  :");
        int a=Integer.parseInt(br.readLine());
        int re,c=a,j=0;
        while(c>0)
        {
            c=c/10;
            j++;
        }
        int rem,d=0,n=a;
        while(n>0)
        {
            rem=n%10;
            d=d+(int)Math.pow(rem,j);
            n=n/10;
            j--;
        }
        if(d==a)
        System.out.println("Yes,It is a Disarium Number");
        else
        System.out.println("No, It is not a Disarium Number");
    }
}

[Question 3] ISC 2017 Computer Practical Paper Solved – Caesar Cipher.

Question 3: Caesar Cipher  is an encryption technique which is implemented as ROT13 (‘rotate by 13 places’). It is a simple letter substitution cipher that replaces a letter with the letter 13 places after it in the alphabets, with the other characters remaining unchanged. Write a program to accept a plain text of length L, where L must be greater than 3 and less than 100. Encrypt the text if valid as per the Caesar Cipher. Test your program with the sample data and some random data: Example 1 INPUT :  Hello! How are you? OUTPUT :  The cipher text is: Uryyb? Ubj ner lbh? Example 2 INPUT :  Encryption helps to secure data. OUTPUT :  The cipher text is: Rapelcgvba urycf gb frpher qngn. Example 3 INPUT :  You OUTPUT :  INVALID LENGTH SOURCE CODE    import java.io.*; import java.util.*; public class ISC2017_CaesarCipher {     public static void main(String args[])     { ...

Pattern of your own name.

Pattern program of your own name. This is a pattern program, in this program you just have to enter your name and it will give you output in a particular manner. I have created this program when I was in class 10th for my Computer Application project. NOTE:  If you are copying my code then its a advise to you to copy it after downloading it to avoid any kind of compilation error its link is available at the bottom of source code. SOURCE CODE import java.io.*; public class Patter_of_your_Own_Name { public static void main(String args[])throws IOException { int time=1; BufferedReader br=new BufferedReader(new InputStreamReader(System.in)); do { System.out.print("\n\t\t\tPLEASE,ENTER YOUR GOOD NAME IN CAPITAL LETTER           :"); String str=br.readLine(); int flag=0;
