#include <iostream>
#include <cstdlib>
#include <vector>
#include <string>
#include <algorithm>
using namespace std;

class RegisterOp
{
private:
   vector<char> reg;

public:
   int size;
   RegisterOp(int si);
   int insert_register(string s1);
   int right_shift_op(int num_rs, char vvalue);
   int left_shift_op(int num_ls, char vvalue);
   int getregistersizeValue();
   void setregistersizeValue(int val);
   int print_regis();

RegisterOp::RegisterOp(int s1)
{
   size = s1;
}

int RegisterOp::insert_register(string s1)
{
   for (int i = 0; i < size; i++)
   {
       reg.push_back(s1[i]);
   }
   reverse(reg.begin(), reg.end());
