{
int number =1234;
int reverse = 0;
// for storing the result and initially made it to be 0;
while(number!=0)
{
int rem=number%10; //Step -1
System.out.println("Now remainder is : " + rem );
reverse = reverse*10 + rem; //Step -2
System.out.println("Now reverse is : " + reverse );
number=number/10; //Step -3
System.out.println("Now Number is : " + number );
}
