In today’s Div2 contest,

I was able to solve questions A, B, and C easily. I took a lot of time on D1 and finally submitted it after around 2 hours. After that submission, when I saw the number of accepted solutions for D2, I felt that it was not for me. I was also feeling bored and a little demotivated, so I cleaned the code of D1 and submitted it again at around 2:30, thinking that only the first submitted code would be considered.

Later, I noticed my rank dropped from around 2k to around 3k. That made me anxious, so I asked ChatGPT about the judging rules on Codeforces. It told me that only the first accepted submission is considered and that after judging, my rank would be based on that. Being confused and trusting that explanation, I resubmitted questions A, B, and C without really thinking about the consequences.

Now I am writing this after the after-contest judging is done, and I feel completely terrible. My initial accepted submissions are skipped. My ranking changed from around 2k to 7k. It honestly hurts. It feels like a small misunderstanding and a moment of carelessness cost me a lot.

And now, because of this, I will be able to take part in tomorrow’s Div4 contest, which I originally wanted to do, but not like this. I didn’t want it to happen because of a mistake. It feels bittersweet and disappointing at the same time.

update: got -75, new rating is 1401 so will even not be able to participate in upcoming div4 contest

i was scrolling the standings of round 1056 div2.

and noticed two accounts with same name in it "animesh", animesh_288 and animesh_demo1. just by looking at the name it's obvious that it would create doubt that is the person using these two accounts together in a contest same.

so, i looked on his submission history and here are the things i observed that made me use the word "cheater"

• animesh_288 has many previously skipped Questions. submission history
• animesh_288 has no wrong answer verdict in this contest but animesh_demo1 has which looks like he is using animesh_demo1 for checking if his code is correct or not

• every submission done from animesh_288 came after it's done from animesh_demo1

• so having all these things against animesh_288 i checked the resemblance of the code submissions made from the two accounts and i found them exact same though animesh_288 has mainly used java and animesh_demo1 has used c++ .

here are the submissions done in round 1056 div2

problem D, 342083650 and 342077506

problem E, 342086949 and 342088002
