Parallel binary search (Solar lamps) | IOI preparation #5

I'm showing a solution for Solar lamps, problem from POI. The technique is called parallel binary search. I didn't remember that and used a name "divide and conquer over queries" in the video. And you need some geometry too. Problem link: https://szkopul.edu.pl/problemset/pro...
