So I was just scrolling the leaderboard and opening random solutions, just when I came upon a code submitted by tourist and the code contained the time of creation of code.

I guess it is dynamically generated, can someone tell me how it is done?

The problem Interactive Tree appeared in contest and I came up with a logic which I think is correct. But the code is not getting accepted. Can someone help me with the code?
