A few days ago, I was looking through submissions from round 1062 (div. 4) to check for cheaters. I had the random idea to search for submissions made to a problem after AC. Surprisingly, there were plenty of times where people got AC on a problem, and then submitted completely different code to the same problem a few minutes later. kundan_kumar_v and venkatsatish03 did this. There were also some users who got AC and then decided to submit incorrect solutions for whatever reason? The most interesting was Mr_prince_sahu, who spent 30 minutes programming 3 different solutions to A in 3 different languages. All of this makes me wonder why would anyone do this?

Now, I have submitted after AC before (in round 1011), but that was for preparing to solve F2. In round 1062 though, there were no multi-part questions. I thought that they were maybe trying to fix some bug and avoid FST, but that wouldn't require one to reimplement the entire solution from scratch, especially since most didn't even have any changes in logic.
