Lecture 2: Data Structures and Algorithms - Richard Buckland

Second lecture of COMP1927 Algorithms and Data Structures, which is the second course taken by first year computing students at UNSW. This course follows immediately on from COMP1917.

What a great prof. that really knows how to break, organize and pass down information to everyone's different level of understanding. You are good man.

[Liminal]

I came online looking for process modeling. After going through heavy-accent, hard-to-understand slides from well-meaning Indian instructors, Richard Buckland is a breath of fresh air. He makes learning exciting, effort-less. Thank you Prof. buckland!

[klasp]

A very powerful teacher, smart use of metaphors and visualization to demonstrate his point. Makes his lectures gripping to watch and listen to.

[DaRRoXX]

Just thought I'd mention, I'm a comp sci student at a different university here in England, and I find this guy's lectures to be extremely informative and interesting, and fantastic revision for my exam (tomorrow) on this topic tomorrow. Oh, and my coursemates agree with me on that. So thanks to the uni for putting these up.

[GamingJediPwns]

Richard, thank you so much for recording your lectures. You are really helping my programming and you also make the lecture interesting which is more than can be said for some of my old lecturers.

[NeilKelly_is_angryexpat]

i just love watching excellent teachers in action, rock on richard

[singh]

i wish that i had teachers like Richard. He has made learning so much easier and fun.

[deluvas]

It's a pleasure watching him ... unfortunately, not all the people are like him!

[QuanSai]

This guy is the man. Period. If all of your professors are like this, I want to attend classes as a registered student at your university. I love you guys.

[prashantd]

I would have bothered if our lecturer was even half as interested as him. Man those kids are lucky, I hope he hasn't lost his passion

[TreborTheWise]

omg, i actually watched another whole video of his again, lol, i love him

[Grymyrk]

I second that, he is a very good lecturer. I am lucky I have had a few lecturers like him in my time at uni.

[Potentilz]

44:20, the most important thing out of the entire lecture (and probably Computer Science) if you're pressed for time.

[theLichKing]

he makes you love programming.. i took computer engineering and programming seemed like a boring thing that we needed to know.. i wish i took my programming classes with him

[emesen_]

the mistake around 43:00 had me spending two hours trying to understand the formula for calculating bubblesort passes. only after concluding i did't get it did i continue, to immediately learn that i was right all along.. Sigh.. Mr. Buckland is by far the best teacher i have had the privilege of watching youtube videos of

[igoronline]

I "third" that =p. If I had the money, I'd leave Brazil for Australia just for Richard's classes.

[GamingJediPwns]

The formula for calculating how many comparisons a bubble sort has to do is actually (n(n+1) /2) - n. Well it does that many in my program anyway.

[TreborTheWise]

once again, i find myself watching one of Richard's classes, even though im doing mech engineering and I go to a completely different uni :p, if only i had lecturers like him...

[jameshook]

This is going to be interesting, much better than school. where were you when I was a student

[dorinbulin]

Ex: 1+2+3+4 = (4+1) + (2+3) this is equivalent with: 2 * (n+1) cause both sums are equal with the first( the last element n + the first element 1); equivalent with :
(n*(n+1)/2)
