Deleting a Node in a Linked List | Animations, Examples and Code | Study Algorithms

honestly speaking ur the best guy in KZbin till today who thought the linked list so easily and with minimum time

[@AiCorrales]

Nikhil Lohia is the GOAT. I once saw him save a entire family from a burning car after saving a drowning puppy. He also helped me get through my Grad CS class. Thank you Nikhil, you are everyone's hero.

thanks, Nikhil, you have made, SLL so simple, now i can visualize things related to SLL. thanks, bro

[@nikoo28]

Thank you so much. Always remember, visualisation of any problem helps to understand better 😄

[@imamit100]

@@nikoo28 thanks, nikhil, bro, I want more favor from you side coz its magnetic what you teach, that, similar to SLL and DLL, please make complete videos on Arrays 1D and 2D, strings, recursion , two pointers, hashing, bit manipulation, etc, concept, syntax and dry run. And , club all questions in a separate video, so that, all concept learn in one and practice them in another. It will synchronize our concept building. Array and string videos you uploaded, are just one. I hope u got the point. Coz , I want to DSA once and forever and no other good source m looking now other than you which fill the gap. So brother just come up with that. Thanks.

Hey Nikhil, I have seen some of your videos. Your videos are really great. Your way of speaking, your pace and style of explaining any problem is marvelous. Thanks for the detailed explanation. 🖖🤩 However just a note for this deletion video here and the other insertion one, while deleting/adding the node from/to the link, you considered the index from 1 while explaining, but from coding perspective, it starts from 0. 🙂

[@nikoo28]

thanks for your feedback and motivation. I understand the confusion it might have caused. Sometimes, it is easier to explain in a certain way and writing code in the other. I will try to clear things up more in my upcoming videos.

[@nageshnimmala3200]

Tq for your effort to make it easy

[@pareshhere]

nicely explained thanks

[@deepeshreddy4700]

how to pass parameters from main method to delete the values it's not present in your code

[@nikoo28]

that would mean deleting a value, thanks...I will cover that portion in another video soon.

[@sourabhajoshi2129]

very nice.. Thank you

[@sharminator5227]

sir at 10:14 the loop should run till i < pos - 2 and not till pos - 1 . Please can you check it once ?

[@deepeshreddy4700]

Thanks Man

[@Ocean_Tales_]

thanks !

[@mdmursalin4546]

Why do we return head from the method ?

[@nikoo28]

That is because we can only refer a single linked list from the head pointer. If we return any other node, the head will be lost.

[@amirhossein8956]

Great

[@infinite639]

circular linked list please teach

[@nikoo28]

I will add a video on circular linked list

[@soothingminds8866]

public ListNode deleteAtMiddle(ListNode head, int position) { ListNode ptr = head; // If position is 1, call deleteAtBeginning and return its result if (position == 1) { return deleteAtBeginning(head); } // Move to the node before the one to be deleted for (int i = 0; i < position - 2; i++) { ptr = ptr.next; } // Get the node to delete ListNode nodeToDelete = ptr.next; ListNode nextNode = nodeToDelete.next; // Point the next of ptr to nextNode ptr.next = nextNode; return head; }
