Now I can say my Nonlinear Data structure journey has been started with Anuj Bhaiya 🙏🙏🙏🙏🙏 Thank You Sir ❣❣❣❣.
Never knew that this medium level topic is going to be so easy for me Thank yoy
You are Such as Good Mentor 🥰 i really inspired your video when did I watch ❤
So easily explained 😍. Thanku.
Very Clean and Neat Explaination,Sir!
You are genious dude…!!! Applauses 👌👌👌
awesome bhaiya, thanks for making coding easier
Nice solution. But i found out a little bit optimization for the above solution. Consider d= horizontal diameter of the tree. Building Treemap takes o(dlogd). Instead of TreeMap use HashMap and maintain two static variables i.e., min and max and update the min and max values as min=Math.min(min,temp.hd); max=Math.max(max,temp.hd); for every iteration. Now traverse the HM from min to max and add those values to a new ArrayList. This will reduce the time complexity from O(n+dlogd) to O(n)

You're right i been thinking the same bro , use min max and hashmap

bro this is correct? void topView(Node *root, int x, map &m) { if (root == NULL) return; if (m.find(x) == m.end()) { m.insert(make_pair(x, root->data)); } topView(root->left, x - 1, m); topView(root->right, x + 1, m); }

Thanks bhaiya
Nice explanation bhaiya
Thanks bhya . I am following you
wonderful
Maaza aa gaya 😁
Thank you so much bhaiya mai yhi same glti kar rha tha.... thank you
loveddddd it
for implementing the queue method we can define three variables in class third one to store level and in the if condition we will check using or operator that if the level of incoming node is lesser than the already existing node it will replace the node. Please tell me if something is wrong with this approach . Open to other suggestions.
Good Solution!
, vertical order, top view, bottom view, what an explanation ☺☺☺
Sir background video recorder app se user Jo video record karta hai kya vo video app Wale ke pass bhi store hota hai kya Kya ye possible hai ki Jo video hum record karte hain vo app Wale ke pass bhi store hota hai kya
what is the time complexity of this solution
can somebody tell me why are we using level order only?

Bhaiyaa DevOps par ek video banaiye isme career kaise banaye
why we don't take preorder traversal for bottom view , kindly give a tree example where preorder traversal gives wrong answer.
❤️❤️
❤❤❤
did u have a computer science degree??
Bhaiya, TreeMap nahi use karke, Map ko sort kardein end me to kaam nahi banega ? :( (Not sure how to implement Treemap in javascript)

Not sure if it is the correct logic for bottom view. Consider this example. 7(0) / \ 6 (-1) 2 (1) / \ / \ 5 ( -2 ) 1(0) 8(0) 2 (2) We have 2 0s at bottom, but the map would hold just 1 zero. So your logic would give -> 5, 8, 2 instead of 5,1,8,2. Or am I missing something?

See the video at 1:07. He talks about when two elements with same distance are met, we pick the right side one. Hence, 8 is picked up!

ans.add(x); } } you need to close extra } , :P Otherwise check the video again on 04:05, where Anuj Bhaiya explains why normal traversal (preorder) will fail

Can someone help me. What if we solve it in this way using DFS? class Solution { static int min=0, max=0; static ArrayList topView(Node root) { ArrayList res=new ArrayList(); Map mp=new HashMap(); helper(root, mp, 0, 0); for(int i=min;i vd) { mp.put(hd, new Pair(root.data, vd)); } } else { mp.put(hd, new Pair(root.data, vd)); } helper(root.left, mp, hd-1, vd+1); helper(root.right, mp, hd+1, vd+1); } } class Pair { int val, vd;// vd represents vertical distance from root AKA depth. public Pair(int a, int b) { val=a; vd=b; } }
