For this upcoming meetup, we will be doing some data structure questions with binary trees. Lot of companies ask quite a bit of binary trees and binary search trees questions. If you don't know what is the difference between a binary tree and a binary search tree, I recommend doing some research and see what are the differences.
Usually, I will be giving out 3 questions on an online sharing app and everyone will be given some time to answer it. Then we will go over the questions together and then move on to the next one. It is definitely recommended, if you know how to code prior to coming to this meetup. Since this meetup is not a beginner course, its primary focus is to help people prepare for the next technology interview.
