I took part in the Codeforces round yesterday, and just now I received a message saying my code coincides with someone else's. I didn't know the person at all. I solved the problem a lot earlier than him, and I didn't share my code to anyone or anywhere. I think it's just a coincidence because the solution is short and the code is simple. Could you please take a look into this?MikeMirzayanov

Upd: fixed author's solution links.

Sorry for the slow Editorial, I am new using Polygon.

Special thanks to TechNite for his help.

About one hour before the contest _cherry_ found the same problem, then we changed it to $$$k=4$$$ and he found another same one again. We are running out of time so we didn't have time for a new one, so we changed $$$k$$$ to $$$5$$$. But we didn't know there is still a similar problem. Sorry again.

I am trying to make problems using Polygon,but I am having problems with pictures.

Can anyone tell me how to add a picture to the problem in Polygon? I am not good at Latex.

Thank you very much.
