从样例输入输出可以很容易看出，输入纸带的每一行是一个ASCII表示的字符，'o'表示1，' '表示0，中间的'.'是个干扰字符，删去即可

写程序每次读一行，算出ASCII码值输出字符即可

#include<iostream>
#include<cstdio>

using namespace std;

char s[20];

int main()
{
    gets(s);

    while(gets(s))
    {
        if(s[0]=='_')
            break;

        for(int i=6;i<=8;i++)
            s[i]=s[i+1];

        int res=0;

        for(int i=1;i<=8;i++)
        {
            if(s[i]=='o')
                res+=(1<<(8-i));
        }

        putchar(res);
    }

    return 0;
}
