题解：‘o’代表 1， ‘ ’代表 0，其他字符无意义，转换成二进制计算ASCII值得到文本。

#include <iostream>
#include <cstdio>
#include <cstring>
#include <string>
using namespace std;

int s[8], flag;
int a[8] = {128, 64, 32, 16, 8, 4, 2, 1};
void fun(){
	int ans = 0, i;
	for (i = 0; i < 8; i++)
			ans += a[i] * s[i];
	char k = ans;
	cout << k;
	flag = 0;
}
int main(){
	char c;
	while(1){
		c = getchar();
		if(c == '\n')
			break;
	}
	while(1){
		scanf("%c", &c);
		if (c == ' ' && flag < 8)
			s[flag++] = 0;
		else if (c == 'o' && flag < 8)
			s[flag++] = 1;
		else if (flag == 8)
			fun();
		else if (c == '_')
			return 0;
		else
			continue;	
	}
	return 0;
