题意：根据输入的字符串，解读成迷宫信息

解题：一开始用字符串来处理，测试OK，但WA；改用字符处理，直接AC。有时问题真得用字符来处理，又简单又高效！

#include <iostream>#include <stdio.h>using namespace std;int main(){char ch;int n = 0;while ( (ch=cin.get()) != EOF ){if ( isdigit(ch) ){n += (ch-'0');} // end ifelse{if ( isalpha(ch) || ch=='*' ){if (ch == 'b') ch = ' ';while ( n-- ){cout <<ch;} // end whilen = 0;} // end ifelse{if ( ch == '!' || ch == '\n' ){cout <<endl;} // end ifelse{} // end else} // end else} // end else} // end whilereturn 0;}
