In this video we are solving probably the hardest question I've ever done on the channel: Count Unique Characters of All Substrings of a Given String (Leetcode 828).
This question is ridiculous... The solution is easy to code but wrapping your head around how it all works is wild and takes a dry-run or two to get because it's a super clever solution but hard to parse on the first time through.
