_Here's a fun question from Marius Dumitran._
_Here's a fun question I've heard recently:_
Website visit counter: Given n log lines from a website, design a datastructure that can answer count_distinct queries efficiently. Log lines are given in sorted order and contain a timestamp (int64) and a user_id (int_64). count_distinct queries have a two int64 parameters: start_time and end_time. For each query you have to return the number of distinct users that have visited the website in the time range [start_time, end_time].
