I like how you first explain the theory and THEN write the code. A lot of youtubers just explain their pre-written code which is not helpful at all.
And the best part about your video is that you gave all variations for the solution! Wow. Crazy good content right here.

[@KnowledgeCenter]

Thanks. Glad it was helpful!

I guess im asking randomly but does anyone know of a tool to log back into an instagram account??
I was stupid forgot the account password. I love any tricks you can offer me

@Denver Elisha Instablaster =)

[@denverelisha7878]

@Nash August I really appreciate your reply. I got to the site on google and I'm waiting for the hacking stuff atm.
Seems to take a while so I will get back to you later with my results.

[@denverelisha7878]

@Nash August it worked and I finally got access to my account again. I'm so happy!
Thank you so much, you saved my account :D

[@Talhaguy]

Watched a few videos and read a few articles on this. This is by FAR the best explanation I've seen and I FINALLY understand it! Thank you!

[@KnowledgeCenter]

Great to hear!

[@kevinle5772]

Can someone explain to me his calculation at 18:35 please?
I thought the sum would just be: 2^0 + 2^1 + 2^2 .... + 2^(n - 1) => O(2^n)
Why does he have: 1 * 2^0 + 2 * 2^1 + 3 * 2^2 + .... => O(n * 2^n), which is much slower than O(2^n)
This really drives me crazy.

[@lockyer8315]

Same bro. Got any solution?

[@janmichaelaustria620]

Thank you good sir! This was probably the best explanation for this problem! You are a god send!

[@KnowledgeCenter]

Thanks.

How would do for subsets ii problem(if it contains duplicates?) in iterative way?

[@raviashwin1157]

Back to back videos ... great job sir...I am completely dependent on you.... can you please upload some videos on linked list

[@Rajat-Sharma1]

Such an amazing explanation!! I was completely able to visualize the recursion!! Thanks!!

[@VenkatIyer]

In the first iteration n=result.size() will give a value of 0 right? How does it enter the loop then? Also, assigning result[i] to r is really cool. I did not know we can assign a value directly to a vector without indexing. Is my understanding correct?

[@yashkute2350]

And how about the power set in lexicographical order?

[@afzalchishti9092]

Amazing video, such a clear and easy explanation. It's apparent from your content that not only do you know what you are talking about but also how to teach!! I have watched a couple other videos for this same problem and no one was able to simplify as you did.

[@KnowledgeCenter]

Thanks a lot.

[@notyet5009]

I wanted the code in C++ but the presentation he nailed it 🔥🔥

[@crankyinmv]

Thanks for that. I was considering the bitmask solution, but was concerned that no limit was shown for the size of nums.

[@arunprasad017]

Thanks for explaining the algorithmic representation before the code. That helped to simplify the recursive solution

[@KnowledgeCenter]

great

[@heyrmi]

This explanation is so clear.

Thanks.

thank u sir ...great explaination
i am new to python , pls tell me at 26:41 how u concatenated lists

[@KnowledgeCenter]

In Python you can concatenate 2 lists with + .
e.g., list1 = ["x", 5, "z"]
list2 = [1, 2, 3]
list3 = list1 + list2 # list3 is ['x', 5, 'z', 1, 2, 3]
