#include <iostream>
using namespace std;

//Function to convert binary number to its hexadecimal equivalent
void solve(int num)
{
    long int hexa_val = 0, i = 1, r;
    while (num != 0)
 {
 r = num % 10;
 hexa_val = hexa_val + r * i;
 i = i * 2;
 num = num / 10;
 }
 cout<<"Equivalent hexadecimal value: "<<hexa_val;

}

//Main function
 int main()
 {
     long int num;

 cout<<"Enter the binary number: ";
 cin>>num;
 solve(num);
 return 0;
 }
