Swap Variables in a Different Way Without Using Third Variables

 Algorithm for Swap Variables in a Different Way:

step 1: Read a, b

step 2: a=(a+b)-(b=a)

step 3: Print a,b

step 4: Exit

Here is the Java Example for Swap Variables in a Different Way:

import java.util.Scanner; 
 public class SwapDifferentWay 
 { 
             public static void main(String args[]) 
        { 
             Scanner s=new Scanner(System.in); 
             int a,b; 
             System.out.println("Enter Two Numbers"); 
                  a=s.nextInt(); 
                  b=s.nextInt(); 
             System.out.println("Before Swap"); 
             System.out.println("value of a is "+a+" value of b is "+b); 
                  a=(a+b)-(b=a); 
            System.out.println("After swap") ; 
            System.out.println("value of a is "+a+" value of b is "+b); 
        } 
 }
