程序代码：

#include <iostream.h>
#include "h.h"
void main()
{
    long int a,b=0,c=1,e=0;
    cin>>a;
    for (;a>=2;a=a/2)
    {
        b=a%2*fun(c,10);
        e+=b;
        c++;
    }
    cout<<e<<endl;
}

#include <iostream.h>
int fun(int a,int b)
{
    if (a==1)return b;
    else return b*fun(a-1,b);
}
