BST+Preoder given just insert elements in tree as per BST property.

[@manishyadav7586]

Thanku so much sir ji ..aap sach me great ho..saare concept topic sab clear ho rahe ab 🙏🙏🙏🙏

[@amanshitta]

Sir, If we design a BST directly using the preorder like the first element is 30 so the next element will be placed according to the BST property and so on... then the post order can be derived using the tree , So why did we need in-order of the tree? because using the pre-order seq. we get to know what is the root element and also the tree itself is a BST so the next elements will be placed according to the property only

[@taleemmurtaza5041]

Sir really you are great amazing trick for find the post order with the hlp of ino and preo😍

[@Reflexes01]

You are the best 😁❤️

[@stutikandpal480]

Sir, I think there is a simpler method. The preorder traversal is given and also it is given that it is a BST, so we can simple create a BST using the keys, and write its postorder. That we will not have to take care of inorder and preorder simultaneously. we need to do this kind of solution only when it's not mentioned that it is a BST. Please let me know if I am wrong. Thank you.

[@suryaprakashtavva230]

[@AmitKumar-te6hy]

Sir now I am able to find order and also construct tree after watching your video. Can we find out order (in order) if (preorder and post order given to us)?

[@priyanshsinha8593]

Sir if the inorder and post order traversal are defined than how will we determine the pre-order of the BST? Please comment and reply and solve my doubt.

[@ghulammurtazagmdahar]

First, using in order and post order draw BST. Second, find pre-order by traversing.

[@amrhosni7175]

[@sejalvinodwasule8868]

🤕😵🤯its still lil confusing

[@ravi12492]

Amazing

[@aliarubab8761]

Thank u soooo much sir

[@deepeshshah4961]

Sir, you said that we can create the BST if we know any 2 of the (Inorder/Pre-order/Post-order) but there is PYQ asked in 1987 which says - "For unique tree, Inorder must be present along with any 1 of (Pre-order / Post-order)"

[@nehamehrotra8555]

Great

[@muhammadmoin74]

what will happen if a inOrder Traversal is given in ALPHABETS and no increasing/or decreasing order is being followed and you have to answer the preOrder from the given choices?

[@aritradas2840]

That's the same problem i am having
