Approaching my recent interviews at FAANG, I have grouped together some of the Data Structures commonly used for solving LeetCode problems. If you are a C#, then you have most likely found out by now that we have no PriorityQueue implementation or Heaps with indexed elements. Still, it’s a great expressive language to use for interviews.
This is by far not an exhaustive list of DS, but enough to cover LC-medium problems.

Cheers!
