C - Decode the tape

Time Limit:3000MS Memory Limit:0KB 64bit IO Format:%lld & %llu

Description

"Machines take me by surprise with great frequency."

Alan Turing

Your boss has just unearthed a roll of old computer tapes. The tapes have holes in them and might contain some sort of useful information. It falls to you to figure out what is written on them.

Input

The input will contain one tape.

Output

Output the message that is written on the tape.

Sample Input

___________
| o   .  o|
|  o  .   |
| ooo .  o|
| ooo .o o|
| oo o.  o|
| oo  . oo|
| oo o. oo|
|  o  .   |
| oo  . o |
| ooo . o |
| oo o.ooo|
| ooo .ooo|
| oo o.oo |
|  o  .   |
| oo  .oo |

| oooo.   |
|  o  .   |
| oo o. o |
| ooo .o o|
| oo o.o o|
| ooo .   |
| ooo . oo|
|  o  .   |
| oo o.ooo|
| ooo .oo |
| oo  .o o|
| ooo . o |
|  o  .   |
| ooo .o  |
| oo o.   |
| oo  .o o|
|  o  .   |
| oo o.o  |
| oo  .  o|
| oooo. o |
| oooo.  o|
|  o  .   |
| oo  .o  |
| oo o.ooo|
| oo  .ooo|
|  o o.oo |
|    o. o |

Sample Output

A quick brown fox jumps over the lazy dog.

题目解析：

'A' = 64+0+0+0+0+0+1

' ' = 0+32+0+0+0+0+0

'q' = 64+32+16+0+0+0+1

'u' = 64+32+16+0+4+0+1

‘i’ = 64+32+0+8+0+0+1

从以上顺序可得出，密码是按照ASCII码

#include <stdio.h>  
#include <string.h>  
  
int c[] = { 0, 0, 64, 32, 16, 8, 0, 4, 2, 1, 0};  
  
int main() {  
    char str[15];  
    int sum,i;  
    gets(str);  
    while(gets(str) && str[0] != '_'){  
        sum = 0;  
        int len = strlen(str);  
        for(i = 2;i < len;i++){  
            if(str[i] == 'o'){  
                sum += c[i];  
            }  
        }  
        printf("%c",sum);  
    }  
}
