一份题目包中的内容[for 出题者]

好久没写东西了，随便灌点水充充门面。

最近总出题，作为一道比较正规的题目，它的题目包中应包含以下部分，我认为：

[] means '1 or more'

* means '0 is okay'

| means 'or'

*[Problem Description(zh_cn)]

Problem Description(en_us)

Additional Parts(img or others)

Data Generator(py or cpp or whatever)

Data(data.in and data.out)

*[Data Checker(py or cpp)]

*[Standard Program(brute-force)]//maybe the same as the one just above

*[Standard Program(AC with no STL)]

Standard Program(AC with total STL)   

*[Standard Program(others')](For Check)
