You should output the hierarchical traversal sequence of this BST.Įach input file contains a test case. Almost complete binary tree can be used in Heap Data Structures. Every formula that is applicable on complete binary tree is also applicable on almost complete binary tree.

Given a series of different non-negative integer keys, a unique BST can be constructed if the tree must also be CBT. Almost complete binary tree is the subset of Complete binary tree(CBT), mean an almost complete binary tree will always be a complete binary tree. A complete Binary tree of height h has 2 h-1 nodes.Out of these 2 h-1 are leaf nodes and rest (2 h-1-1 are non-leaf.Read more about complete binary trees here or watch video.Below are all complete binary trees: rapidquiz questionAll Leaf nodes of complete binary tree are at same level answeryes optionsyesno notesThere is no hole in complete binary tree. The following trees are complete binary trees since they have no. In a complete binary tree All the levels are completely filled except the last level that may or may not be completely filled.

Left and right subtrees must also be binary search trees.Ī complete binary tree (CBT) is a fully filled tree, which may be filled from left to right except for the bottom. A complete binary tree is a binary tree in which all the elements are arranged without missing any sequence.

The right subtree of a node contains only nodes whose keys are greater than or equal to the node keys.The left subtree of a node contains only nodes whose keys are smaller than the node keys.The binary search tree (BST) is defined recursively as a binary tree with the following attributes:
