Inaho! What a wonderful name. Unfortunately, it is also's and 's favourite problem, and so we have decided to mock it by creating 5 more problems named after it!
After the very successful Inaho Contest, we have decided to make a comeback, with 5 new (and improved) problems! These problems will be very obscure, weird, and break the boundaries of your imaginative capabilities, and so we hope you try them out.
Here are the parameters of the contest:
- Contest duration: 3 hours.
- Number of problems: 5, full feedback, with subtasks. Each problem will be out of 100 points.
- Not rated.
- Scoreboard will be visible throughout the duration of the contest.
Clarification requests for the contest must be routed through the clarification system provided on DMOJ, and not through other channels including but not limited to Slack. Furthermore, all clarification requests will be handled the way they normally are in IOI. Note that, in particular, clarification requests must come in the form of yes/no questions.
After joining the contest, you proceed to the Problems tab to begin. You can also go to Users if you wish to see the rankings.
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. The last submission time of your highest score will be used.
Remove all extra debugging code and/or input prompts from your code before submitting. The judge is very strict — most of the time, it requires your output to match 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 is guaranteed that all the problems will be solvable with C++.
Read carefully, and try to attempt all the problems. They may not be as hard as they seem and you may get partial points!
At the end of the contest, you may comment below to appeal a judging verdict. In the case of appeals, the decision(s) of staff is final.
