Hello, recently I received system generated notification that my submission 321526757 for problem 2114E coincides with some random people.

I would like to mention I did not discuss my solution with anyone during the contest, nor did I share it publicly. I genuinely worked through the problem myself and believe I just used a standard dfs approach on trees. You can verify that I took a reasonable amount of time to solve the problems. I have never shared my solution on public sites like Ideone.

I request you to please review. I will gladly provide any further details if needed.

Thank you for your support.
