Hello everyone, I want to report 2 cheaters today.

2 days ago there was CF Round #395 Div2. I participated in contest also, problems were really good. Let's look standings. Hmm, good, 3 people solved all problems, 2 of them are Chinese. ljh2000 and MashiroSky. Ok, I looked their profiles, saw that they are living in same place, studying in same school. Hmm, it doesn't like coincidence. Then I looked their solutions.

Solutions for problem A: ljh2000's solution, and MashiroSky's solution. Looks similar, but it's easy problem, most peoples solutions looks same.

Solutions for problem B: ljh2000's solution, MashiroSky's solution. Hmm, looks similar, but it was easy also, let's see other solutions.

Solutions for problem C: ljh2000's solution and MashiroSky's solution. Yeah, do you see functions? Struct node with "tag" variable, same dfs function, same build function, same query function, same solve function and some of them wrote work function, and other one wrote things in work function in main. THEY'RE CHEATING HARD!!! How Codeforces couldn't catch this?

You can look other submissions too, they are same, but name of some variables changed, cheating like children...

When I see cheaters, I'm feeling sad for people who solved solutions legally, for example squaredog solved all problems too, but he couldn't be first reason of cheaters...

Sorry for poor English.
