Hello Codeforces!
I am thrilled to invite you to the ICPC 2027 Mock Prelims — 1, which will take place on Monday, September 28, 2026 at 17:00 UTC+5.5 (IST).
This contest is hosted as part of the Inter-College Competitive Programming Camp. It is specifically designed to provide a highly authentic ICPC preliminary experience, perfect for finalizing your team's strategy and building contest stamina before the main event.
You will be given 6-7 problems and 3 hours to solve them. The contest will follow standard ICPC rules and scoring.
UPDATE : There will be 7 problems and the problems are sorted in increasing order of difficulty (as per setters/testers) but it is advisable to read all problems.
The contest theme is inspired from my own ICPC team MST's Journey from our college in Varanasi to Kanpur regionals back in 2019.
This round wouldn't have been possible without the contributions of many individuals:
The problems were authored by me (Enigma27) and prepared by Claude.
A huge thanks to our amazing team of testers for their invaluable feedback, rigorous stress-testing, and for ensuring the problemset is well-balanced: s_jaskaran_s, Arnav_Singhal1, aryanc403, lucky__389, Soumil69, Rodger2041 and Divine_Spark.
Thanks to MikeMirzayanov for the excellent Codeforces and Polygon platforms.
To participate, please ensure you have joined the Inter-College Competitive Programming Camp group and registered your team for the contest.
We hope you enjoy the problems. Good luck, have fun, and see you on the leaderboard!

excited for it :)
Contest will start in 30 mins
Shouldn't the icpc prelim contest be of 2 hours? And are the problems supposed to be sorted according to difficulty?
Prelims is of 3 hour only and the problems were sorted in increasing order of difficulty. Though it was a mock contest so we don't actually know if the number of problems and the difficulty will be similar or not but the timing is same.
