?(>_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
Hint
The output of the four sample programs are {“Hello, world!”, “source_code”, “source__codesource__code”, “?(>_o)!Hello, world!”} respectively. Therefore the first two programs are quines, and the last two are not.
Luckily, there is a ‘?’ in the fourth program, so the hardware will not catch fire or explode during running the fourth program.
思路:照着那个表,,出现了什么就打印什么,如果打印出来的东西和原来输入的一样,那就输出Yes, else cout No
