#include <stdio.h> 
  
int convert_0_To_n__(int number, int d) { 
    if (number == 0) 
        return 0; 
  
    int digit = number % 10; 
    if (digit == 0) 
        digit = d; 
  
    return convert_0_To_n__(number / 10, d) * 10 + digit; 
} 
int convert_0_To_n(int number, int d) { 
    if (number == 0) 
        return d; 
    else 
        return convert_0_To_n__(number, d); 
} 

int main() 
{ 
    int number = 1080030; 
    
    printf("%i", convert_0_To_n(number, 7)); 
    
    return 0; 
}
