l The examination time is4hours. After the time expires, contestants cannot continue to submit their answers.

l Before the exam is compulsorily over, players can voluntarily end the exam (identity verification is required), and will not be able to continue submitting or browsing answers after the exam.

l Contestants can browse the answers they have submitted. Copies are allowed for viewed answers.

l For the same question, contestants can submit their answers multiple times, and the last answer submitted shall prevail.

Participants should not write "name", "test number", "institution name" and other identity-related information or other content unrelated to the competition topic in the submitted code, otherwise the results will be invalid.

l Contestants must submit their answers through a browser. Answers submitted by players in other positions or otherwise submitted by players will not be valid.

l There are three types of questions: "Result Fill-in-the-Blank", "Code Fill-in-the-Blank" and "Programming".

Fill in the blanks: Contestants are required to fill in the results directly according to the question description. There is no limit to the solution method. No source code required. Fill in the blanks and submit the answers directly through the web page, without writing redundant content, such as comments and explanations.

Code fill-in-the-blank questions: Contestants are required to fill in the missing parts on the basis of figuring out the working principle of the given code, so that the program logic is correct and complete. The code must be filled in no more than one statement (i.e., there must be no semicolon in the middle).

Fill in the blanks in the code (only the answers in the blanks, excluding the code that already exists on the question) can be submitted directly through the web page, without writing unnecessary content, such as comments or explanatory text.

Programming Questions: Require the program designed by the contestant to give the correct output result for a given input. Candidates have a chance to score only if they can run the correct results.

Note: The input data used in grading may be different from the sample data given in the paper. The contestant's procedure must be generic and not valid only for the given data in the paper.

All source code must be in the same file. After the debugging is passed, copy and submit.

Note: Do not usepackageStatement. It can only appear in the source programJDK1.5syntax or calls. Not available1.6or higher features.

Note: The main class name of the player code must be:Main, otherwise it will be deemed invalid.
