Hello Codeforces Team,
I received a plagiarism warning for my submission (ID: 347728443) on problem 2164B. I want to clarify that I wrote the entire solution by myself during the contest and did not share it with anyone. It seems there might have been an accidental similarity or unintentional code leakage, possibly because I used an online IDE which might have been public by default.
I sincerely apologize if this caused any misunderstanding. I assure you that I respect the rules of Codeforces and will make sure to use private or offline IDEs in future contests to avoid any such issue again.
Thank you for your understanding.

Hello Codeforces Team,
I have tested the examples provided in 216D- Copy String and I wonder if I am missing something. When transforming "vzvylxxmsy" to "vvvvvllxxx", it cannot happen in 3 transformations because "vzvylxxmsy" — "vvvvvllxxx" = "zymsy".
I can't see a rule that defines how two letters can be modified in a single transformation which is the only way to solve it in 3 steps. I wonder what I am missing in the problem description?
