On special occasion of crossing 2048 subs, here is my 2nd special video!

This video talks about Policy Based Data Structures, an unexplored and alien data structure that already exists in C++.

The data structure is capable of:

  1. Adding/Removing elements
  2. Find the K-th smallest element
  3. Find the no of elements less than a given X
