This guy is the best. I can rarely pay attention to youtube tutorials for >5 mins. This guy has me zoned in for 2 hours at a time.

[Arootinr]

Just the fact that you added "and Sorting Algorithms" to the title helped me find what I needed. wonderful class and teacher. thanks for the upload.

This series is amazing. We're so lucky to have this information provided for free!

That chair demonstration was excellent. I could almost visualize the code in my head, good way to think about the logic of sorting.

Thank you for posting this. I am not traditional software engineer, and I would never found this content had you not posted it.

[gordgood]

No one's gonna talk about the amazing intro?

[dinohunter]

He is real teacher, really let the students suggest solutions. Others just tell their "story" then the class is done.

[eliphasmasuka]

I am now at the end pf second sem in my university but This is my second lecture counting from CS50- B, It took us the whole semester to learn what th guy taught in 2hrs. And FreeCodeCamp guys, Quincy and Company thank you is never enough

[kryogyn]

Great video I have a BS in info sys but I haven’t looked at programming for a few year. So I’m refreshing. But this was the best explanation of the various sorts that I’ve seen.

[kqxdddd]

I can see the sweat on his head, he's such a passionate lecturer.

[ManzoorHussain-gzvk]

When I watch his lectures I get so much motivation for study. Thank you, sir.

[sangwookim]

This lecture is increadibly better than my uni's. The lecture is so engaging, fun and so clear. Meanwhile in my uni the lecturer dribbles incoherently over videos used in the past semesters smh

[wassimboussebha]

to convert chars to integers you can do that :
``` char c = 'a'; // narrowing on C
int a = c; // instead of int a = (int) c;
```

[bernhardtrian]

he is literally sweting bullets while his lectures. this shows how motivated he is

[abdullahfurkanozbek]

That log(n) definition was awesome I did not learn that from school.

[leenagupta]

You are very good speaker and teacher 😊

[jking]

That's beautiful enjoyed this very much

[ArulPalanisamy]

Being a BA English student, I watch this video to develop my spoken English skill...Anyway, I understand something about the functions of computer and its parts...

Help me 0.75 playback speed, you're my only hope.
