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.

这题一开始总是runtime error,百度后才发现字符每次都要输出……亏我还弄了个数组,最后一起输出。。。
题目大意:
1 #include<stdio.h> 2 3 int main() 4 { 5 char s[20]; 6 int i, k, n; 7 gets(s); 8 while (gets(s) != 0 && s[0] != '_') //好久没写了。。 9 { 10 n = 0; 11 k = 1; 12 for (i = 9; i >= 1; i--) 13 { 14 if (s[i] == 'o') 15 n += k; 16 if (s[i] != '.') 17 k *= 2; 18 } 19 printf("%c", n); //n用int即可输出字母了 20 } 21 return 0; 22 }
