Thoroughly explained, all the underlying concepts were briefed as well.👍
Appreciate the effort.

[anime__ash]

High Effort content thats all we need
Thanks I finally got it!

[janmichaelaustria]

Thank you much for taking the time to make all the videos! Much appreciated sir! <3

You teach really well. I only have one question - you mentioned separate chaining to address collision issue so I think the codes incorporate this. I'm looking at Python codes. If you do add or remove a key, you search for bucket i. Does this search mean chained keys, if any, at the same bucket are also searched? Thank you.

[ayyappahemanth]

Love your videos as usual. Your videos became my daily routine. If you have some time left please do and explain leetcode 230 along with follow up questions.

[namangoyal]

sir can u make a series of interview preparation it will help a lot!!

[abhishekchaurasia]

Thank You So Much...Nice and Simple explanation !!

[siddharthsingh]

best explanation and moreover got to know more about hashing

[vinoltauro]

can you explain the initialisation of vector in the myhashset constructor ? great explaination by the way.

[genghisda]

Sir under which CS topics do we study about about Hashing and separate chaining and open addressing.? In which book can i find about these ?

[rohangangwar]

one thing i don't understand is why you take 15000 as numbuckets ??

[maheiramkhan]

What happens if I make the hash_function() public?

[myaseen]

Sir for recording of video which software you are using

[bhawansingla]

What if all the keys are mutiple of 5? Then, all the keys will go into a single bucket. The complexities will be O(n) then.

[debarghyachakraborty]

Sir will you consider making more videos of the Rust programming series ?

[DevMaster]

Nice explanation. But why you have chosen numbuckets =15000? why not some other number? could you explain the way to choose optimal value for numBuckets?

[genghisda]

i dont know why i feel i had seen "design hash map " video on this channel, now i cannot find it, , is it deleted ?

[alxx]

What software do you use to write on the screen?

[kollivenkatamadhukar]

I didnt get why used num buckets = 15000 could you please explain

[cloud]

Just a "funny" solution (don't take seriously):

class MyHashSet {

boolean[] array;

public MyHashSet() {
array = new
}

public void add(int key) {
array[key] = true;
}

public void remove(int key) {
array[key] = false;
}

public boolean contains(int key) {
return array[key];
}
}

Lol
