?(>_o)! is a pseudo-object-oriented programming language. It implements the following commands:
| Command | Description |
|---|---|
| ? | Check whether the character '?' is in the program's source code. If '?' does not exist in the program's source, the hardware will catch fire or explode. |
| ( | It tries to match ')', although mismatch of brackets does not matter at all. |
| > | Increase the internal accumulator. |
| _ | Print the program's source code. |
| o | Instantiate an object of a new sub class of the generic super class. Due to the best principles of object hiding, this object cannot be accessed in any way. |
| ) | Just matches '('. It's for patient with obsessive-compulsive disorder. However, mismatch of brackets does not matter at all. |
| ! | Print "Hello, world!". |
| Other characters | Be treated as comments rather than instruction. |
However, it's only another joke programming language. There is even no way to access the accumulator. But it's one of easiest to finish a "Hello world" program or a quine program. A quine
is a computer program which takes no input and produces a copy of its own source code as its only output. Your task is to judge whether a ?(>_o)! program is a quine.
Input
There are multiple test cases. The first line of input is an integer T indicates the number of test cases. For each test case:
There is one line of string represents the source code of a ?(>_o)! program. The program contains no more than 256 characters. The ASCII value of each character is within [32, 126].
Output
For each test case, output "Yes" if it is a quine. Otherwise, output "No".
Sample Input
4 Hello, world! source_code source__code ?(>_o)!
Sample Output
Yes Yes No No
代码：
#include <iostream>

getchar();

for (i = 0; i < strlen(all); i++)
in += all[i];
string ans = "";
for (i = 0; i < strlen(all); i++)
{
if (in[i] == '_')
ans += in;
else if (in[i] == '!')
ans += "Hello, world!";
}
if (ans == in)
puts("Yes");
else
puts("No");
}
return 0;
