4 Data Structures You Need to Know

Data Structures are a staple in software engineering. You will not be able to do any real programming without them. There are about 7 data structures you absolutely need to know, and in this video, we discuss 4 of them.

I'm 61 years old. Recently retired nurse anesthetist....started working towards a Masters in CS Online....just finishing my first semester...doing great. Just wanted to say I love your channel and have been following you over the past few years and I found your channel very inspiring and even encouraged me to finish my CS studies that I migrated away from over 30 years ago. DSA course coming up next semester. Every little bit up the good work!

I am not religious, but Jesus telling me he is proud of me for clicking on this video does make me proud of myself

4 Data structures are:
Arrays
Linked Lists
stack
queue

This is perfect, I am at hash tables in my Uni algorithm course right now so need that part 2 as soon as possible. Much thanks

[JustinPBarnett]

LOVE that these are pre-built into most languages nowadays. Makes coding SO much easier 🙌🏻 Your vids are amazing, Forest! Keep up God’s work

I'm doing data structures right now in uni and you helped A LOT, please upload another one with the rest structures you mentioned

I much prefer this sort of content regarding programming rather than the "pro tips" for landing that coveted FANG software engineering job, etc. As you mention in the video, its easier to dream about getting a job in software than it is to sit down and do all the nuts-and-bolts grunt work to gain a deep understanding of what software can do and how it's implemented. So, I personally would prefer it if you made a lot more videos like this one. BTW, I'm a big fan of the Open Source Comp-sci degree. I'm a totally noob, and I'm slowly working my way through it during the lockdown. Thanks for all your efforts, Forrest!

Yeah. I want tree + heap = whatever you're telling

I don’t know if it’s your lack of intimidation on the subject matter, your Germanic lineage, or simply your beard that makes these elusive concepts make so much sense!!! Or maybe I’ve been banging my head away at this keyboard for too long, but I want to thank you for your effort.

About the intro, I think alot of people would like to learn, but when on YouTube you're just surrounded with so much more entertaining and interesting things that it's hard to click on something that is likely to be purely educational. Even I only clicked because I have an exam about Algorithms and Data structures in two days...

As a computer science graduate and professional for 3 years, I could say that you really are a nice teacher. Also please add more visuals to beginners. For example you would have added three different linked list graphics while you were talking about them.

*In JavaScript:* An element inside an array can be of any type, and different elements of the same array can be of different types: string, boolean, even objects or other arrays. This means that it’s possible to create an array that has a string in the first position, a number in the second, an object in the third, and so on.
JS is awesome.

This intro is absolute genius.. I already clicked on the next data structures video and I haven't even finished the first one

[litpapi]

I had an interview yesterday and the interviewer asked me to name some data structures and what they are used for. TAKE NOTE YA’LL. 💻

[bragiodinsen]

He coded and was buried in bugs. On the 3rd day he rose again. He optimized into heaven and is seated at the right hand terminal. He will come again to review the promoted and the dead.

checking in, in 2022. Your channel is the only one i can watch and learn from. Everyone else has no people skills at all

[TuRaTic]

FINALLY A MAN I CAN UNDERSTAND, HE TALKS IN METAPHORS AND EXPLAINS THE & PLAYED WOW ERMAGERD TAKE MY MONEY

[michaelk]

Actually have a midterm for my data structures class on monday, just went over stacks and queues. This was a great condensed refresher on what i’ve just learned. Could not have been better timing so, thank you! :)

When Jesus Christ starts teaching you programming tutorials on YouTube, you know - The End is Near!

Absolutely loved this video getting ready to start to work on a bachelors in Computer Science and felt these are useful and interesting
