Crack your Next Interview - Let's ease it a bit by learning Data Structures

Hey guys,

I am back with my new article. In this article, I will briefly touch upon my upcoming tutorial series on my YouTube Channel where I will be covering the most commonly asked interview questions pertaining to Data Structures and Algorithms.

A couple of videos of this series are already out. So here is how the entire video will be structured.

Each video will first explain the problem that we will be solving, then we will think about a couple of approaches using which we will solve the problem. Finally we will write the code together and do a dry run analysis for each of the codes that we write.

WHAT EACH OF THE VIDEOS WILL CONTAIN ?

Here are some screenshots showing what we will be doing for each of the videos.

We will be solving problems on a lot of other topics. Some of the topics that we will be covering are

⚑ Arrays
⚑ Strings
⚑ Hash Maps
⚑ Trees (Binary Trees, Binary Search Trees)
⚑ Graphs
⚑ Linked Lists

⚑ Stacks and Queues

⚑ Matrices

I will be happy to see you onboard !
