This contest will cover some basic algorithms and problem-solving.

The organizers for this contest are: Steve, isaaclu and QuantumFlare.

• The contest will consist of 4 questions around the difficulty of CCC J3-S2.
• Contestants may ONLY consult official language documentation.
• This contest will be rated for all users.

Clarification requests for the contest can either be routed through the clarification system provided on TSSOJ.

Any suspicious behavior will result in being forcibly ranked at the bottom of the scoreboard.

The contest consists of 4 questions in order of difficulty from easiest (J3 level) to hardest (S2 level). It is highly recommended to read all of the problems. After the contest window begins, you may begin at any time. You will be able to submit until the hard deadline at 11:59pm Sunday.

After joining the contest, you proceed to the Problems tab to begin.

We have listed below some advice as well as contest strategies:

• Start from the beginning. Ties will be broken by the sum of times used to solve the problems starting from the beginning of the contest.
• Remove all extra debugging code and/or input prompts from your code before submitting. The judge is strict — your output must match the judge output exactly.
• Do not pause program execution at the end. The judging process is automated. You should use stdin / stdout to perform input / output, respectively.
• It should be guaranteed that all the problems will be solvable with C++, PyPy3, and Java (Use fast input as the regular scanner may TLE).
• Read and try all the problems!!! Maximizing subtasks is the best way to guarantee a higher score!

At the end of the contest, you may comment below to appeal a judging verdict. In the case of appeals, the decision(s) of our staff is final.
