Byfar the best linked list series Thank you very much Raj Bhaiya

Thanks for clean code. sudo code have minor issue , please correct it . if ( t1 -> data < t2 -> data ) You missed equal elements . it should be if ( t1 -> data data )

yes. I wondered the same. I came here from leetcode. there some values in the two sorted lists which are same. but what an explanation. I know only basics of linked lists. I was able to undersand well enough

There is no need for this Equal to condition bcz it already handled by else part But it is good to think about this condition👍👍

@m1stnoob201 5 ай бұрын

Can't we use dummy node to make it as a copy of the lowest head value of either of the lists (which acts as the head of the new merged list) , and repeat the same process . Will the solution be different ?

@justsomeguywithoutamustach9978 5 ай бұрын

To be exact, time complexity would be O(min(n1 + n2)).

@atulwadhwa192 8 ай бұрын

shouldn't time complexity be min(n1,n2) coz this is where while stops and then it's just one extra link that we've to do?

@shahidullahmuffakir668 7 ай бұрын

if the smaller values were in the n2 then in this case we will traverse till the end of n2. so min(n1,n2) will not work.

@Mel-up7un 13 күн бұрын

But we have to consider the worst case in which we traverse both the linked lists up to the last node

I'm confused how the space complexity is O(1)? We are creating a dummy node which extends to hold the nodes of both linked list 1 and linked list 2. Don't the space complexity be O(n1+n2) where n1 are number of nodes in linked list 1 and n2 are number of nodes in linked list 2.

we are not creating a new node we are just declaring it like a temp node

There's a little mistake at the end for handling remaining nodes after either one list has reached null, there should be a another while loop to handle those cases. Also there isn't a java code to the above problem kindly provide one

@gokulanvs 10 ай бұрын

No need for while loop , see the video 11:40

@md.ualiurrahmanrahat2400 9 ай бұрын

No,we don't need the while loop here. As we are using the exiting nodes itself,not creating new ones. Suppose n1 is null, so n2 is left. we pointed temp->next as n2. so, from here, link is maintained up to n2 becomes null. Hope you got this.
