A quick brown fox jumps over the lazy dog.

题意：解码。

思路：7位的二进制。

AC代码如下：

#include<cstdio>#include<cstring>using namespace std;char str[100];int main(){ gets(str);  while(true)  { gets(str);    if(str[2]=='_')     break;    else    { int k=0;      if(str[9]=='o')       k+=1;      if(str[8]=='o')       k+=2;      if(str[7]=='o')       k+=4;      if(str[5]=='o')       k+=8;      if(str[4]=='o')       k+=16;      if(str[3]=='o')       k+=32;      if(str[2]=='o')       k+=64;      printf("%c",k);    }  }}
