题意：其实就是二进制相关的计算。'o'表示1,' '(空格)表示0比如第一组数据

| o  . o| 一共有8位，不包括'|'和'.'那么就算的值就是2的6次方+2的0次方=65对应的字母是'A'..

知道怎么做就是卡。还是要加大代码量啊 

 

#include<stdio.h>
#include<string.h>
int main()
{
 char s[20];
 int a[]={0,128,64,32,16,8,0,4,2,1};
 int i,sum;
 while(gets(s))
 {
  if(s[0]!='|')
   continue;
  int len=strlen(s);
  sum=0;
  for(i=1;i<len-1;i++)
  {
   if(s[i]=='.')
    continue;
   elseif(s[i]=='o')
    sum+=a[i];
  }
  printf("%c",sum);
 }
 return 0;
}
