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 Output

A quick brown fox jumps over the lazy dog.

对应的是二进制啊。。。那个 . 没有意义。总共7位，o 代表1，空格代表0（zero）

|  o  .   |

代表空格。。。翻译过来就是0100000，是ascii的32

#include <stdio.h>
#include <string.h>

int a[11] = {0, 0, 64, 32, 16, 8, 0, 4, 2, 1, 0};

int main() {
	char str[20];
	fgets(str,20, stdin);
	while (fgets(str, 20, stdin) && str[0] != '_') {
		int num = 0;
		int len = strlen(str) - 1;
		for (int i = 2; i < len; i++)
			if (str[i] == 'o') 
				num += a[i];
		printf("%c", num);
	}
	return 0;
}
