Paid - Data structures course - Hashtables and Trees (Re run)

Re run of the class run in early December.

Introduction to Hash Table, Trees

• What is a Hash? Implement a Simple Hash Function

• What are Hash Collisions?

• Overview of Map Interface 

• Hash Maps, and Big O for operations

• Introduction to Trees

• Binary Search Tree Construction (Code BST)

• Tree Traversal (DFS/BFS)

Note: Please bring your laptop. We will be using Java for our coding, and strongly recommend installing JDK and Eclipse if you already have not done so yet.


Is this class for me?

This class is for you if you are looking to understand these data types. Focus is on building the foundation needed to Ace the coding interviews. We will code some of the algorithms, based on which you can solve interview questions.

We may discuss a few interview gotchas.

If you are looking to practice these data structures, I recommend joining the free meetups and request the facilitators for questions using these Data Structures.

    OK, thanks for that info, Vivek. I'll try to make it for the entire 3-hours then.

    Hi Murthy,
    The DS class is 1 hour, 5:00 - 6:00. That will be followed by our regular meetup (2 hours). The objective is pretty different for these two sessions.

    DS class helps you build fundamentals.
    the Free meetup helps you by getting you a lot of interview practice.

    How long is this class? I got an invite for a 3-hr meeting, but I see another meetup scheduled for 6:15pm. Are they hosted by different folks?
    I can't make a 3-hr session tomorrow, hence the Q :-)

    Will this meeting do more than just basics? For eg, will we go over actual interview questions on hash tables and trees?

Meetup has allowed me to meet people I wouldn't have met naturally - they're totally different than me.
