How do you implement a complete binary tree in python?
In this tutorial, you will learn about a complete binary tree and its different types. Also, you will find working examples of a complete binary tree in C, C++, Java and Python. Show
A complete binary tree is a binary tree in which all the levels are completely filled except possibly the lowest one, which is filled from the left. A complete binary tree is just like a full binary tree, but with two major differences

Python, Java and C/C++ Examples
Relationship between array indexes and tree elementA complete binary tree has an interesting property that we can use to find the children and parents of any node. If the index of any element in the array is i, the element in the index Let's test it out, Left child of 1 (index 0) = element in (2*0+1) index = element in 1 index = 12 Right child of 1 = element in (2*0+2) index = element in 2 index = 9 Similarly, Left child of 12 (index 1) = element in (2*1+1) index = element in 3 index = 5 Right child of 12 = element in (2*1+2) index = element in 4 index = 6 Let us also confirm that the rules hold for finding parent of any node Parent of 9 (position 2) = (2-1)/2 = ½ = 0.5 ~ 0 index = 1 Parent of 12 (position 1) = (1-1)/2 = 0 index = 1 Understanding this mapping of array indexes to tree positions is critical to understanding how the Heap Data Structure works and how it is used to implement Heap Sort.

How do you create a complete binary tree in Python?The following are steps to insert a new node in Complete Binary Tree.. If the tree is empty, initialize the root with a new node.. Else, get the front node of the queue. ……. ... . If the front node has both the left child and right child, Dequeue() it.. Enqueue() the new node..

How do you insert a complete binary tree?Complete Binary Tree Inserter in C++
insert(int v) will used to insert a TreeNode into the tree with a value node. val = v so that the tree remains complete, and returns the value of the parent of the inserted TreeNode; CBTInserter. get_root() this will return the head node of the tree.
