Hi Everyone,

I want to start preparation for product based companies...currently I can solve basic question of DS like stack,queue,array, basics of trees and recursion.

Problem is that there are lots questions in a given topic and I am not very sure, which to solve first.

I want help from this community to get some good question from Advance Data Structure that I must solve.

Example:

• Frequently asked questions in Product Based Companies
• Different types of questions from a topic covering different scenarios

Please suggest your points also for the preparation

Thankyou All
