Contest Rules
Individual Participation – The contest is strictly for individual participants. Any form of collaboration or discussion during the contest is prohibited.
Strict Prohibition of AI Tools – The use of any AI-based tools, including code generation or problem-solving assistants, is strictly forbidden. Any participant found violating this rule will be disqualified and removed from the rankings.
Plagiarism and Malpractice – Any form of code plagiarism, sharing of solutions, or unauthorized assistance will lead to immediate disqualification. The organizing team reserves the right to take necessary actions in such cases.
Contest Registration: Registration for the contest will open 6 hours before it begins. To participate, ensure you are a member of this group and have completed your registration.
Scoring and Ranking: The contest will adopt a binary scoring system. The rank of contestants will be determined by the total number of problems successfully solved by the participant, and the total time taken to solve the problems. A penalty of 20 minutes will be added for each incorrect submission on a problem before it is solved. Problems are organized in increasing order of difficulty to provide a progressively challenging experience for participants.
The problem set will consist of 7 problems, and participants will have a total of 2 hours and 30 minutes to complete them.
The problem set will consist of a mix of difficulty levels, designed to test your skills in algorithms, data structures, and problem-solving. Make sure to manage your time wisely and aim to solve as many problems as possible within the given time frame. Good luck, and happy coding!
We’re excited for you to try the problem set and wish you the best of luck. See you on the leaderboard!
Best regards,
Computer Coding Club, MNNIT
