[@todayscreator8662]

Bhaiya linked list m thoda sa confusion hora tha starting m par fir do teen video dekhne k baad ab maje aa rhe h linked list k questions karne m

[@sangrambiradar9461]

Hello guys, it doesn't matter how smart or dumb or lucky you are, if you are consistent enough you can outwork all the people who you think are talented or smarter than you. #consistancy #linked list

[@vishalplayzz2580]

🙂yeah man u are right

[@suyashjain3223]

3 different Approaches for Single Question. Itna to koi paid courses me bhi nhi btata .Thanks a lot bhaiyaa ❤❤❤

[@shikharverma5824]

we know you are observing a constant decline in views,but its just because we are left behind and your content is amazing,Thanks for creating the content and for your efforts

[@259_parthpatidar9]

yes correct

[@piyushsharma6505]

No one can match the commitment and dedication of Love Bhaiya towards teaching and making sure we comprehend the concept easily

[@dudamneerajdattu1459]

33:04 after listening to this approach, i was like 🤯🤯, aisa kaise soch bhi sakthaa hai

[@harsh55]

pheli bar gfg pe love bhai ka solution dekhe bina one shot mein probelm nikal li (of course approach 1 se) . Inutution a raha hai . Thank you! you rock

[@ayushkushwaha171]

Maine khud se bhi kaafi socha for any brute force approach. I was very close to the solution that u provided. Really felt amazing by my improvement. Thanks bhaiya!

[@computerguy3550]

BHAIYA JI BOHOT TEZZ BOHOT HI JADDA BADIYA APPROACH 3 MAZA HI AHHHGYA, APPKI ENERGY EK ALAG HI LEVEL HAI THANKS BHAI.👌👌👌👌

[@Mb-nr5nz]

Aapka content itna acha hai bhaiya ki aisa lag raha hai aap placement laga ke hi chodoge , waise abhi aaphi ka video dekh raha tha pointers wala , kya easily samjhaya hai , thanks big brother ❤️

[@sahilsoni4299]

placement hui fir?

[@Ayush_.]

i watched this video 2 times 🤩🤩fir bhi borring nhi laga just bcz of your amazing explaination bhaiya 🔥🙌

[@varun-qm3xj]

pushing limits... last approach me maza he aagai bhaiya code krne me

[@suvigyabasnotra7378]

sections of code to the original diagram/ approach you've made on the iPad...? Requesting this because it gets unnecessarily hard to visualize all the code so fast mentally! In other words, explain each of the lines of different sections of code, comparing it with the iPad approach after you're done coding. Explain like... this line is doing this and this one is doing this, back in the approach rather than just simply wafting over the sections like at 54:07 which we already understand. This method of teaching would really help and prove to be icing on the cake for a lot of us. Thanks for your consistent efforts!

[@iEntertainmentFunShorts]

Bhaiya m thoda peeche chal rha tha qki Maine 450 and leetcode k problems bhi lagayei Linked list pr toh frequency slow mat krna, map wali approach toh Maine khud se sochi thy but jo 3rd approach thy that was like 🔥🔥 PS: Thank you so much bhaiaya this question was like🔥

[@ankitsaha675]

Shaaandaaar series chal rha h bhaiya. 🔥🔥

[@atharvakadam4701]

Though the video was long but I couldn't get such a great explanation in any KZbin video! great content.

[@shiriii-x9h]

Love this course🥰... live talk se motivation => reminding to be consistent in course😇

[@eshaanpandey7353]

Hashmap solution was easily understandable, I won't remember Approach 3

[@anushkayachit]

mai to kal mazaak me boli thi video chahiye.... aapne to sach me daaldi... kya aadmi ho yarr 😂😂 chalo anyway.... thank you🖤🖤

[@uttamkesarwani6143]

We need Handwritten Notes rest of Lectures, It's really time savings. When we have to revise, then I think all of us use that beautiful Notes. Otherwise it again a long time to see video again.

[@akashsharma9674]

khud bana le na bhai.

[@JatinKumar-w7f]

class was really amazing and I felt it very cool in coding, Thanks sir for this one and truly speaking, This is the first time that I am saying someone thanks for this kind of teaching. Thanks to make these video and it is helping me a lot in getting my goals.😊😊😊😊

[@prashantbirajdar9271]

wahh bhiyaa maja aa gyaa..❤ sub smaj aa gya hume 🤩🤩👍👍

[@singhharsh8019]

Thank you bhaiya for providing nicest dsa content and it's quality is just the best out there....No other course even come close to the simplicity and quality of this content....so thank you again and keep going

[@aryansen2410]

solid lecture babbar bhaiya

[@keshavarya7918]

Sahi video bana di 👍👍.......isme rehti thi mujhe thoda confusion

[@fahadabdullah687]

babbar bhai absolutely loved loved loved.... the way you built it...Just one thing, please don't use red to write things down on dark background...use some other colors which make contrast better and readable.

[@dhanushsingh9541]

Best DSA series out there thank you for this😊

[@Spike_104]

51:25 nahi aa sakta upar waale logic me temp->next me NULL. Kyunki temp traverse to original list ke element ko kar raha hai aur Har original node ke baad uska clone node toh ana mandatory hai to temp -> next kabhi bhi NULL nahi hoga kyunki wo humesa apne clone ke counterpart ko point karega.

Thanks bhaiya for this explaining this amazing question... mja hi aa gya aapse ye question samajkr

[@AA-wy9vw]

Loving the series.

[@aayushgoswami8632]

Hiii.. just one suggestion -> at 46:40 you can also use while(temp != NULL){ if(temp -> arb != NULL){ temp -> next -> arb = temp -> arb -> next; } else{ temp -> next -> arb = temp -> arb; } temp = temp -> next -> next; } because temp -> next won't be equal to NULL ever.

[@sagardebnath8842]

Correct ✅

[@akshatmalviya8563]

Yes , the condition of temp->next getting NULL will never be true . We can remove also

[@righttoright829]

yo yo yo question me maje aa rhe hai

[@shreyanshthakur5405]

Hey guys, do you guys code along with bhaiya and submit the solution Or you code by self after watching the lecture ? Just curious about different study approaches.

[@utkarshpatidar167]

2nd one..

I watched first video of yours to understand basic concepts of linked list then I open leetcode with linkedlist structured problems then I end up by finishing that with finishing this playlist .. lol 😂 great work .. it took me around 1 month to understand concepts of linkedlist and in this my oops concepts were also brushed up

[@heybiplabb]

Present bhaiya ✋

[@arijitgarai7077]

There is another simple approach we can solve this problem only with the insertAtTail function by passing the random pointer as an argument. Like this - class Solution { private: void insertAtTail(Node* &head,Node *&tail, int val, Node* random){ Node* newNode = new Node(val); if(head == NULL){ head = newNode; tail = newNode; newNode->random = random; } else{ tail->next = newNode; tail = newNode; newNode->random = random; } } public: Node *copyList(Node *head) { Node* cloneHead = NULL; Node* cloneTail = NULL; Node* temp = head; while(temp != NULL){ insertAtTail(cloneHead, cloneTail, temp->data, temp->random); temp = temp->next; } return cloneHead; } }; Now on gfg it is random no longer arb.

[@sandeepn7378]

Love babbar bhaiya is op

[@rahulrastogi5312]

Present bhaiya 🔥🔥❤️

[@suvigyabasnotra7378]

Could understand the 2nd approach but not the code like around 22:18 . In the next ones, can you please explain each line of code back in the diagram on the iPad once you're done coding...? Because it gets harder to visualize so much code mentally and ultimately hard to keep track of what step does what behind the scenes.

[@himanshu_1422]

class Solution { private: //insert function for inserting nodes in clone list void insert(Node* &head , Node* &tail , int data){ Node*temp = new Node(data); if(head == NULL){ head = temp; tail = temp; return ; } else{ tail->next = temp; tail = temp; } return; } public: Node* copyRandomList(Node* head) { Node* temp = head; Node* clonehead = NULL , *clonetail = NULL; while(temp!=NULL){ int data = temp->val; insert(clonehead , clonetail , data); temp = temp->next; } map mp; temp = head; Node* p =clonehead; while(temp!=NULL && p!=NULL){ mp[temp] = p; temp = temp->next; p = p->next; } p = clonehead; temp = head; while(p!=NULL && temp!=NULL){ p->random = mp[temp->random]; temp=temp->next; p = p->next; } return clonehead; } };
