In the last Div 4 contest, there was an interactive question 1807E - Interview. It was my first encounter with such a problem. After the contest, I tried to make my own interactor locally in Python. But, I wasn't able to get it working. I also asked this question in stackoverflow, but I didn't receive any answers till now. If anyone from here can guide me, then I'll be really grateful.

Thank You.

Update: Someone answered my query on stackoverflow. Thanks for trying if you did.
