#include <stdio.h>

int add_odd_digits(int n, int second_n);
  
int main(void)
{
    int n = 12734, second_n = 100;
 
    printf("%d\n", add_odd_digits(n, second_n));
         
    return 0;
}
  
int add_odd_digits(int n, int second_n)
{
    int multiply = 1, odd = 0;
     
    while (n != 0)
    {
        if (n % 2 != 0)
        {
            odd += (n % 10) * multiply;
            multiply *= 10;
        }
        n = n / 10;
    }
 
    return second_n * multiply + odd;
}
