Practical No -2(a)

AIM – Write a program to implement Railfence algorithm.

public class railfence

{

              public static void main(String args[])

             {

                        String input = "inputstring";

                         String output = "";

                        int len = input.length(),flag = 0;

                        System.out.println("Input String : " + input);

                         for(int i=0;i<len;i+=2)

{

                                     output += input.charAt(i);

                        }

                        for(int i=1;i<len;i+=2)

{

                                       output += input.charAt(i);

                        }      

                        System.out.println("Cipher Text : "+output);

            }

}

OUTPUT-

Input String : inputstring

Cipher Text : ipttignusrn
