OMG ..Your video was soooo helpful. Keep going !

[@muhammadfaizan3645]

Dude, u deserve a huge applause for this great work. keep it up bro...

[@MrSzkrumpirro]

Great! Finaly I understand how to solve my tests :) Thanks!

[@ravikumarkommi5477]

Great Work Now I understood Pre, Post Oders

[@jatinkumar-gh3no]

Please Explain the Preorder from Postorder also...

[@baskaranbaluchamy3667]

Sir really very great explanation .... Thanks lot...

[@monu4349]

[@sureshkaragana7934]

Thanks alot sir very useful

[@anuragkumargupta7506]

Thank you sir . How we make binary search tree using in order traversal.

[@bilalmirza9118]

What if the tree is not BST??? Abcd are given instead of numbers?

[@bilalamin273]

what if the in-order is given only how can you construct only from the in-order?

[@sunnyjain630]

Sir, is there any way to convert this pre to post OT without construct BST.....!!

[@ShubhamSarda]

Thank You For This Awesome Explanation!!!

[@saadyousaf6243]

apne bthaya k left me hamesha smaller values athi hay but aissa zrooori b to nahi agar large ajay pir

[@sunnyjain630]

thanks,plz improve sound and vidoe quality.....

[@kunjuraj1]

really a good video...... thanks a lot dude........

[@rayabanerjee6759]

now i understand it clearly ! thnak you!

[@vishuvyas9716]

Thank you so much sir

[@kyleh6516]

Nice explanation!

[@sumithreddy1088]

clear explanation THANKS!!!

[@pularirecipe9241]

given preorder 5, 3 ,1 ,2,4,6,8,7 find postorder pls do wit step

[@soumi6720]

There is a very disturbing sound going on in the background bt explanation is good but hard to focus

[@ajay.chawla]

what if the nodes are alphabets ?

[@harpreetsandhu7697]

yes please tell what if it's alphabet

[@ajay.chawla]

Harpreet Sandhu you can compare two numerical values and accordingly build a tree but what if alphabets are used?

[@nou4605]

ASCII values perhaps ?

[@michrisoft]

this is a binary search tree. You can't do a binary search tree with the alphabet. That would just be a binary tree.

[@barbabietola]

Chris Jantzen yes, you can if you appoint values to characters (imagine a = 1, b = 2... or use ascii, after all chars are represented and evaluated as ints), or just assume they are sorted in alphabetical order (a > b > c...) you can do bst with any data as long as there is a key that you can sort the data by in the terms of smaller/larger.

[@saxena3718]

you are a saver...........thnx man!!!!!

[@abdullahkhalid9581]

Whats that background noise in the video?

[@saxena3718]

please upoad a video for AVL trees....plz

[@MohdYaseenmas]

nicely explained.. thank uuu

[@aniketpagar2229]

nice explanation

[@SatyasriPedasingu-ue6nn]

What if letters are given in place of numbers

[@priyanshasharma6158]

very well explained !

[@kmamatha3792]

How do u know sir that sequence is pre order or post order

[@akSingh_120]

great sir..

[@vishnushingala9924]

Draw the tree whose postorder traversal is c,b,f,e,g,d,a.

[@indrjeetrajput9170]

Pls solved the postorder DEBFCA TO preorder

[@ashish_more]

very helpful

[@allasairam94]

if the order is not in BST?

[@sateeshv928]

Well explanation

[@bipinkori4060]

What is the sound noice ,disturbed

[@dimplejain7226]

what if nodes are alphabets???? there you cannot have less than or more than..???

[@yuva434]

Thank You

[@akshaygupta2863]

sir,please explain if the order is not BST then how we solve these kinds of problems

[@AP-eh6gr]

+Akshay Gupta if it is not a BST then one preorder representation can give multiple trees. so no one will ask you such a question

[@AmitParopkari]

awesome man!

[@applesanish]

BEST EVER

[@prathammehta9167]

Thanks bhoi

[@tusharkantighorai6701]

Thanx bro

[@kunalkhoche5476]

ek no

[@Tanzeel431]

thkns a lot sir

[@shariaretanvirakash8716]

what if the root is 1 then how to calculate ?

[@barbabietola]

shariaretanvir akash same as this, but the left subtree will not exist (unless you have values smaller than 1 such as 0.5 or negative numbers etc)

[@sh1lpa785]

thank you :D

[@rocco9t9]

great

[@mayyashobary1812]

Thanks

[@hardiksharma7100]

cool man

[@RupeshKumar-eo1mi]

how can you know that 5 element in leftSubTree and only 4element in Right SUbTree.... (ye kya RATA hai kya...)

[@sidhantgupta2996]

since those 4 elements are greater than 12 i.e. root node, they are at right subtree.. Get your facts clear before giving a negative comment on someone

[@michrisoft]

I have no idea what "ye kya RATA hai kya" means but the part in english was a question, not negativity?

[@MdJunaidSiddique]

It means "Have you memorized this!".

[@anshulthakur3806]

Chris Jantzen, rata means "root learning method of child"

[@bipinkori4060]

@@MdJunaidSiddique yes

Noise is too much 😢

[@akshaygupta2863]

sir,please explain if the order is not BST then how we solve these kinds of problems

[@huangzach9276]

+Akshay Gupta I think there might be no solution if tree are not BST. Could have mulitple tree have same pre-order results
