Binary tree :- Any tree with max two child nodes

Full Binary tree:- Any tree with a given level h having 2^h-1 elements

complete binary tree : if we start removing elements from full binary tree ( 0 or more from rightmost leaf node )result will always be a CBT 

almost CBT : it is a complete binary tree in which  last level is not full (i.e at least one element has to be removed from full binary tree)


BST  is based on values values in left are less than root and values at right are more than root



12              45

for balanced BST refer

@snajay sir is it allowed in almost CBT to have all the childrens on the RHS parent without filling up Left parent .
no left child must be there for corresponding right child but converse is not true e.g following tree is not almost CBT



                 d           e
but in your paper pen explanation first exp from bottom it has lest child but no right chile . but on the next parent node you have given both child without filling up previous right child of lest node
Ya in bottom last part how can we show both left child as well right child of parent until unless we dnt put right child of  parent being at the same level
