唬人题，其实很水。。处理下两种字符就可以了，其他的全不用管

#include<iostream>#include<string>using namespace std;int main(){int T;cin >> T >> ws;string s;while (T--){getline(cin, s);string res;for (size_t i = 0; i < s.size(); i++)if (s[i] == '_')res += s;else if (s[i] == '!')res += "Hello, world!";cout << (res == s ? "Yes" : "No") << endl;}return 0;}
