$$$\textbf{Details:}$$$
- The computer can only be used to code and compute.
- Participants will be required to submit the final answer to the problems along with the code/brief calculations through Google forms.

Update 1: This is the submission link. For any clarifications during the contest, either mail your queries to [email protected] or join exactly one of the WhatsApp groups below and ask the admins. Please do not join more than one link.
The problemset will be available in the form link once the contest is live, and we will also share it here when the contest starts.
Update 2: The contest has started, and the form link is up. The problems can be found on the form link or here.
Update 3: The contest has ended. The editorial can be found here.
We would like to thank MikeMirzayanov for the great system Polygon and Codeforces, and you all for participating.
Looking forward to seeing you all in the standings. Make sure you read all the problems carefully. Good luck and have fun!

Is there some Group where we get the link which i have to join??
No, you just need to register for the contest.
Contest link?
++
We'll update the contest link soon on the blog and also send an email to the registered participants!
Is it rated?
No, the contest is not rated!
Reminder: The contest starts in 10 minutes from now!
Only one of my teammates is able to access the contest. Rest have not received any mail.
Your teammate has probably registered for the mashup individually and not as a team. Please register as a team at the mashup link shared in the update (of the blog). You will be able to access the contest then.
We have registered as a team only
Can anyone share their solution for E?
I was trying to find all the numbers <=10^5 that are divisors for >= n — 1 numbers and was then trying to check if that could be a possible gcd for a spanning tree by trying to visit all nodes through edges that are a multiple of that number. As expected this approach was giving tle.
Thanks for the great participation in ICPC de Tryst! The editorial can be found here (or here, in case for some reason the previous link is inaccessible).
We encourage you to participate in CodeMod 2022 as well!
Reminder: CodeMod 2022 starts in about 1 hour and 15 minutes from now. Registrations are still open (and will be open till 45 minutes from now)! Details related to submission logistics will be updated soon and sent via email to registrants as well.
Edit: The contest logistics have been updated in the post. The email will be sent out soon.
Quite irresponsible of you guys to make the email ids of all participants public like this, there's a thing called BCC, smh.
We accidentally sent the emails without BCC. We are extremely sorry for the blunder.
Thanks to everyone who participated in CodeMod 2022! The editorial can be found here. Feel free to discuss alternative approaches!
