BINARY SWAP BETWEEN TWO NUMBERS

 Given two numbers'x' and 'y'.write a program to print number of digits needed to be

 flipped convert 'x/' to 'y'

  I/P:

  7 10

  O/P:

  3

SOLUTION:

package Numbers;

import java.util.*;

public class Bitswap {

    public static void main(String args[])

    {

        Scanner sc=new Scanner(System.in);

        int n1=sc.nextInt();

        int n2=sc.nextInt();

        String s1=Integer.toBinaryString(n1);

        String s2=Integer.toBinaryString(n2);

        

        if(s1.length()<s2.length())

        {

            s1="0"+s1;

        }

        else{

            s2="0"+s2;

        }

        int count=0;

        for(int i=0;i<s1.length();i++)

        {

            if(s1.charAt(i)!=s2.charAt(i))

            {

                count++;

            }

        }

        System.out.println(s1+" "+s2);

        System.out.println(count);

    }

}
