there are few nicest guys in competitive programming community or in general programming community like William Fiset from google who loves to share their knowledge. No doubt Errichto is one of them with clear understanding and full control on programming. Keep up.

good question was asked at @32:26 and nice answer "looking for third and fourth elements in quadraple". This helps to simplify implementation and can be applied to other questions as well like dynamic programming questions.

Its my observation that in most of the problems which asks about 3 indices Meet in the middle works

Just curious if anyone was looking for nlogn solution using fenwick tree. since we are looking for number of elements which are less than b on left hand side and greater than b on right hand side, we just need to maintain two fenwick trees one for left side view and one for right side view. Using sweep line we can maintain both dynamically and calculate answer.

In the four sum problem wouldn't the count of pairs with distinct positions be wrong if there are duplicates for example for this input 8 15 3 2 3 2 8 1 3 2 ans is 12.
