原标题：编程马拉松 | Hackathon is coming！

一转眼已经开学几周了

In a flash, we have been in school for a couple of weeks

你有没有在学业的鸭力下喘不过气呢

Have you breathed under the pressure of academics?

在数不清的DDL来临之前

Before the countless DDL comes

小C为大家带来了一年一度的

CPU编程马拉松活动！！！

Cpu organizes the annual event—

Hackathon

一样的赛制，不一样的是你们标新立异的程序

The same is the competition system, the difference is your innovation.

或许你会问：

“我没有基础可不可以参加比赛？”

You might wonder: whether I could take part in the competition without learning programming before?

完全没有问题！！！

No problem at all

这绝不是程序猿的专场

This is not designed especially for programmers

只要你有一颗热爱编程的心

As long as you love programming

我们会为你们准备相关的培训资料

We would provide relevant training material for you

帮助初学者更快入门

Help beginners start faster

相信在你和另外两名队友的共同努力下

We believe that under the cooperation of your teammates

一定能将精美礼品收入囊中！

You would get beautiful gifts!

活动时间

10.28 2-5pm

活动地点

PMB(SEB)432

(或等大其余教室)

比赛规则Rules

·本次比赛所使用编程语言的范围限定为：C，C++，Java 和 Python。

· 每个队伍由 3 人组成参赛; 如果不够 3 人，可单人报名，CPU 将帮助你随机组队。

· 本次比赛将提供网络，您可按需使用；但是请不要在比赛中使用任何通讯软件。

· 每个团队只能使用一个参赛账号。最终应通过网络平台 online judge 提交。题目得分将由开源系统自动评判，保证比赛公平性。

· 对于每个问题，您应提交一个源代码文件。源代码文件中的输入输出以及语法要求请参考样例。

· 请注意每个问题的时间限制和内存限制。请优化您的程序以满足这些要求。

· 请只输出所需的答案。不要打印任何额外的信息。

· 此比赛不允许使用多线程、输入输出重定向等任何试图绕开题目要求的方法。

本活动最终解释权归CPU所有

Rules for Hackathon:

The scope of the programming language used in this competition is limited to：C, C++, Java, and python.

We expect a three-man team to take part into this activity, but if you cannot make a three-man team, just sign up individually, we will help you find your teammates.

Internet access will be provided but do not use any communication software in competition.

Each team should use no more than ONE account. The final work should be submitted to the online judge. The score will be automatically judged by the open source system to ensure the fairness of the competition.

For each question, you should submit ONE source code file. For specific input/output requirements and formats please refer to sample programs.

Please note the requirements of time limit and memory usage. Optimize your algorithm to meet these requirements.

Please ONLY output the required answer. DO NOT print any extra information.

Please do not try breaking the limit of the questions by employing multi-threading, input/output redirection or any other methods.

For more details, please refer to Rules for Hackathon.

Note: Any violation of the above rules would result in a zero mark for that question.

The final interpretation of this

activity belongs to the CPU.
