I think you like to write mini stories, but... I lost myself few times... 2 hours took me to solve this... I don't think the mini-books should be on 8kyu lvl.

I miss the part

return the number of people who sit strictly behind you and ||>>>> in your column <<<<|| or to the left, assuming all seats are occupied.

But what about the fact that I interfere with people in my line (col) !!!

Maybe im stupid but it took around 5 minutes to me to get the part about column being inclusive and row being exclusive. Got it only after manually putting finger on kata image.
