We invite you to participate in CodeChef’s Starters 193, this Wednesday, 2nd July, rated for all users.

Time: 8:00 PM — 10:30 PM IST

Joining us on the problem setting panel are:

Written editorials will be available for all on discuss.codechef.com. Pro users can find the editorials directly on the problem pages after the contest. The video editorials of the problems will be available only to Pro users.

Also, if you have some original and engaging problem ideas, and you’re interested in them being used in CodeChef's contests, you can share them here. Hope to see you participating.

Good Luck!

Note: The problems are based off the Indian IOI Training Camp 2025. As such, there might be more unusual problems, and more subtasks. If you have participated in the camp, or know the problems in some other way, please do not participate.


Congratulations to Top 5 in Div1!

What's the point of posting this here if you aren't going to respond to genuine queries? It seems like the contest is restricted, look into it.

Almost the same problem as MEXTREEMX already existed:

1292C - Xenon's Attack on the Gangs

The only difference is that in one problem it was necessary to label the vertices, and in the other — the edges. The idea for the solution in both problems is the same.

I think this is similar to Mex tree min, except for in the Mex tree min we have to find the sum
