I was looking in the [Codeforces Round 1065 (Div. 3)](https://mirror.codeforces.com/contest/2171/standings) standings and I spotted a very suspicious user.↵
↵
Their account is [user:casualuse1045,2025-11-21].↵
↵
What's suspicious is that just 10 days before Codeforces Round 1065 he participated in **Codeforces Round 1063 (Div. 2)** **solving 0 problems** but in **Codeforces Round 1065 (Div. 3)** he solved all problems, and even in other div 2 contests he barely even solved 1 problem which is a really suspicious rise in solving ability in just 10 days and is impossible to attain by anyone.↵
↵
Also in problem **H** and **G** he used↵
↵
~~~~~↵
while (t--){↵
function_name(); //just a placeholder↵
}↵
~~~~~↵
↵
While in the other problems he used↵
↵
~~~~~↵
while (t--){↵
// all code in the while loop itself↵
}↵
~~~~~↵
↵
Now both these things are really suspicious and they suggest that the code was copied from elsewhere. I think this account should be looked into by [user:reirugan,2025-11-21]↵
