15:31 difference need to repeat the add part for the other set. A and B difference is not just A not in B as in the code, but also B not in A.
that rword variable aged pretty well
Is it enough for getting job in big mnc company as a mern stack developer??
Please reply someone??
I have doubt for the difference() function for Set. Will it include those values which are in other set but not in first set?
can anyone explain how this function recursion works in this function, how left function call and right function call inside function works and provide us 1 or 2 for unbalanced and balanced tree.. It will be great help if someone explains as I was not able to understand with explanation on this video. Duration of the content after 46:00
findminheight(node = this.root)
if(node == null)
let left = this.findminheight(node.left);
let right = this.findminheight(node.right);
if(left < right)
return left + 1;
return right + 1;
The difference of sets algorithm only works when the shorter set is passed into the function because you use the first set to check for difference. That’s not proper because in real cases, you don’t know exactly what’s in the sets.
Set1 = [2,3]
Set2 = [3,5,6,7]
In your implementation,
set1.difference(set2) returns 
Set2.difference(set1) returns [2,5,6,7]
Shouldn’t you test which set is longer and then use it to check for the difference?
If you implement it that way,
set1.difference(set2) returns [2,5,6,7]
Set2.difference(set1) returns [2,5,6,7]
How rword will have the reverse order of the word. can antbody explain please
Thank you so much sir ❤️
at min 38:25, what if the child were 0 instead of 4? Wouldn't it be violating the rules of the BST, since the node containing 0 would have left child greater than 0 (1)
that was fun af never imagine I could understand that
Thank you 🙏
I didn't really expected to understand this, but now I finally am able to really understand these concepts! Thank you very much!…
One important message to all of the people who are trying to understand or having difficulties in understanding this:
How can these algorithms used in the real world?
Great lesson Mo, A minor correction In BST example though (video at 36:56)…. Since BST is always sorted, node "23" can never have a right linking to a lesser value (in this case "19"). In this scenario value "19" should not be there at all. Also, removal of node in BST can be revisited. The replaced value should be the max of the subtree (so 23 can be safely treated as a new node to be replaced in left subtree for your scenario) . Happy Coding!
great tutorial man! one comment, the bst delete is missing something. what if the value to replace the 17 is on the left and not the right. we need to recursively search here too?
This is why I will probably never become a programmer. I just can't watch a 1h52min video staying focused. Just the length of this video is so demotivating for me. 😮💨
I'm going through this course and I just can't speak enough of the efforts and quality of these videos. Beau is an amazing instructor!! And thanks again for putting this together.
Good teachers dont copy and paste code. Teach every bit of the code u are typing that's best way to teach. Nonetheless thanks for the effort that's why I gave a like.
It's just awesome
Hello Mrs Clara the bitcoin trader is legit and her method works like magic I keep on earning every single week with her new strategy
learn by doing
keep up the good work
keep up the good work
what are api request
Why do you need a heap to sort numbers when you can just use the array prototype sort and pass in a function that returns a – b
@36:39 Why do we need to go node.right? And then node.left? Can anyone provide an explanation?
What keyboard and mouse are you using?
the sounds are really nice 🙂
seto kaiba rules!!
pop OOOF 🤣😂😂😂 every time you said that made me more focused on the topic, Thanks Beuau
Learning this in my job, thank you!
May I know about which IDE or interactive coding website is used in this course?
Play at 2X speed. Thank me later.
Can you improve the video quality? Or can you make a new video?
This video is obviously not for beginners. Nice video though, cheers
this is a great video! I really needed this. Typing the code out as you explain it can be helpful for retention and slowing down when you do write the code. Similar to your python and SQL videos.
Hey. Bo is great.
You should code and show instead! and tell at that time the flow
Is there an advanced course? 😆😆😆
Beau you are the best
Excellent! This is just the coding video i needed right now 🙂
I am 26 . Should I learn coding and can I get the job in software industry..
