[@Gaurav_63]

so some little corrections that i found were : 1. At 53:20 approx in this tree you took 3 leaf node and 4 internal whereas it was opposite 2. if no of leaf nodes are 'n' then the min height has to be log(n) 3. if 'n' nodes in total min possible height = log(n+1)-1 [not log(n+1)

[@abhay80324]

yes sir right

[@workHolic-ne6eo]

also he said root node is not internal node. which is false

[@BhaweshPandey-u9w]

@@workHolic-ne6eo No, root node is not an internal node.Tthe root node is a special case of a node that does not have a parent, and it is not classified as an internal node.

[@SujeethVarma]

@@BhaweshPandey-u9w The Formula ( no.of leaf nodes = 1 + no.of internal nodes with 2 childs) holds true only if we consider root node as an internal node..... at 55:00 kunal took leaf nodes = 4 but it's actually 5

2:10:05 I think we don't need to check whether the left subtree or right subtree is balanced or not because we are maintaining the height of every node while insertion , hence those function calls will be redundant ( if it's wrong please correct me 🙂 ) ( I am able to write this because of Kunal's great explanation ) thanks to Kunal ❤

51:26 there are actually 4 leaf nodes right? the left most node? in that case the formula holds true. leaf nodes = internal nodes + 1 4 (leaf nodes) = 3(internal nodes) + 1; inserting a node 4 - 1 + 2(new leaves) = 3 + 1(old leaf now internal) => 5 = 4 + 1
