Bro just look at C. I am specialist from my original account and I couldn't solve C. Due to this mf cheaters I am getting a rank of 5k+. It may be easy but I guess not so easy that more than 4k people can do it within contest..............

HIGHLY DEMOTIVATING(crying emoji)

    Maybe the question wasn't too difficult to solve, but 5k+ solve is not usual. Maybe the question wasn't too difficult to solve, but 5k+ solve is not usual. Few of my friends who are also actually specialist are unable to solve this.

      My spec friend solved this... he did better than me several times already though, but still.

      (I've dodged the contest, but C looks difficult :D)

        it is not! basically, you do a dfs from node 1. in the dfs, (let's call current root i), you ask about every node (let's call it j) in your subtree. if the x=i, you can safely add the edge [i, j], otherwise, ask again about j when you reach x. and recursively dfs into every neighbor of i. this works in nlogn, becuase the distance between i and j is halved every query.

              agree bro, wished they applied their intelligence in solving the problem instead of covering those in this manner. (I kinda feeling bad about the complier which will compile this solution (laughing emoji))

      D actually could be coded in 20-25 minutes without a segment tree if you read well and didn't fuck up in de-abstracting your implementations.

Normally, when I solve two problems, I find myself ranked between 9000 and 10000. But this time, I found myself at 15000, so I believe there are at least 3,000 cheaters in this contest.

    It depends on the time as well. For example, in my case: I could submit A by 00:06, and B by 00:13 (both by general observation only though). I did not (or maybe I should say could not) solve the next ones though. Even after I solved only 2 questions, my rank is still approx 5.6k.

I (from this account) was in room no. 96 and harshita_iit was on the leaderboard. She solved D 277388242. Clearly her template is different from what she submitted for other two and previous contests. Moreover it matches with https://www.youtube.com/watch?v=uCJiwQbc9Wo&t=98s as well as many other submitted code 277417264, 277416791, 277416913 and god knows how many. She has clearly used chatgpt to change variable names as wells as write comments.

It came to my notice as she was in my room and was on the leaderboard of my room.

I wanted it to write on blog but since I have no access to write it, I wrote it here.

EVEN IITIANS HAVE STARTED COPYING

SHAME

The data of D is too weak. Some people passed it by going through every value each time, which can have a complexity of $$$O(n ^ 2)$$$.

This submission by user rajneesh_neo clearly seems to be faulty ..

it clearly has been copied from 277400319 by user keyur14113

using some AI tool , just the variable names have been changed.. rest of the structure remains exactly same..

Kindly look into this MikeMirzayanov

Cheaters should be banned because they pose the biggest threat to the community. Although I may not have much influence or experience, I believe that competitive programming is all about the adrenaline rush—the sadness of a wrong submission and the joy of an accepted one. If someone is truly passionate about competitive programming, they should focus solely on these experiences and problem-solving.

The real enjoyment of competitive programming comes when someone participates in contests and solves problems without worrying about their rating. One cannot improve if they are stuck in the loop of obsessing over their rating. Sooner or later, these cheaters will be banned, and at the very least, people from the programming clubs of institutes should monitor this behavior or teach students to either engage in competitive programming honestly or explore other fields, so they don’t harm this community.(just a random thought or maybe a vague idea)

I used to get under 3k rank last year then I stopped CP for a year, after I restarted, I could feel that I improved, solving higher rated problems but now I am being ranked below 7k in all contests I gave.
