Hello everyone. At yesterday's div 3, the 25th place was taken by a user with the nickname crymath. I was interested in seeing his solutions, so I went through all his completed tasks. I was confused that the names of his variables are too painfully complicated for the task set in the first minute, especially since he uses std::, which obviously does not add to his speed of writing code. (And he also used "\n", which is even more strange for a task completed in 60 seconds. I looked at the code for his second task, which was completed 3 minutes after the first, and my suspicions began to show there. Using long long in every similar variable, instead of, say, typedef ll or something similar. And also, out of nowhere, std::iOS appeared for quick input, although this was not the case in the first task. Next, I went to the third task, which was completed 6 minutes after the second, and was surprised. Huge code with complex variables, using unsigned. In general, the remaining tasks, except the last one, do not differ in any way in the style of the code from 3. When I opened his code for the last task, I just couldn't believe that a person could come up with and write it in 9 minutes since the last eye + he abruptly switched to bits/stdc++

after that, I decided to go into his previous attempts (https://codeforces.net/submissions/crymath), and I think I understood everything. His first built solution has a using namespace std;, but that's not the main point. there are literally gpt comments in Russian. The rest of his codes only confirm my hunch that this man is using more than just his head.

if there are mistakes in the text, I'm sorry, I used a translator, have a nice day.
