UVA 10878 - Decode the tape

很有趣的题目,其实每一行都是一个字母的ASCII码的二进制表示,o表示1 空格表示0

#include <iostream>#include <string>#include <memory.h>#include <cstdio>using namespace std;const int conPow[]={1,2,4,8,16,32,64,128,256,512};char buf[100];char toDecimal(string & str){char v=0;for (int i=str.size()-1;i>=0;--i){v=v+(str[i]-'0')*(conPow[str.size()-i-1]);}return v;}int main(){gets(buf);while (gets(buf)&&strcmp(buf,"___________")){string bin="";int len=strlen(buf);for (int i=0;i<len;++i){if(buf[i]==' ')bin+='0';else if(buf[i]=='o')bin+='1'; }printf("%c",toDecimal(bin));}return 0;}
