 HOW TO REVERSE A NUMBER

take varible 

1. int number; //to store original or to get quotient
2. int rev; //to decrease the number
3. int reverse_number = 0; //to store reverse number

• First take input from user.(number=5364)
• then run one while loop condition while(number>0)
• under loop rev = number%10;
• //we get rev =536
• //take another variable reverse_number
• reverse_number = reverse_number*10+rev;
• //we get reverse_number= 4
• number=number/10;
• //now number= 536

import java.util.Scanner;

public class Main {

        while (number>0) {
              rev = number % 10;
              reverse_number = reverse_number * 10 + rev;
              number = number/ 10;
