看看代码就懂啦~。

记得要向上取整~

#include <cstdio>
#include <cstring>
#include <iostream>
#include <algorithm>
const int MAXN=10000;
using namespace std;
int main (void)
{
    long long num;
    while(~scanf("%lld",&num))
    {
        if(num<=9)
        {
            printf("Stan wins.\n");
            continue;
        }
        if(num>9&&num<=18)
        {
            printf("Ollie wins.\n");
            continue;
        }
        while(num>18)
        {
            num=(num-1)/18+1;
        }
        if(num<=9)
        {
            printf("Stan wins.\n");
            continue;
        }
        if(num>9&&num<=18)
        {
            printf("Ollie wins.\n");
            continue;
        }
    }
    return 0;
}
