We all know tree is a non-linear information construction. It has no limitation on the variety of little one. A binary tree has a limitation as any node of the tree has atmost two kids: a left and a proper little one.
Introduction to Full Binary Tree:
A binary tree is alleged to be a whole binary tree when all the degrees are crammed fully besides the bottom stage nodes that are crammed from as left as attainable.
Some terminology:
Properties of Full Binary Tree:
Excellent Binary Tree vs Full Binary Tree:
A binary tree of top ‘h’ having the utmost variety of nodes is a good binary tree.
For a given top h, the utmost variety of nodes is 2h+1-1.
A full binary tree of top h is a correct binary tree as much as top h-1, and within the final stage ingredient are saved in left to proper order.
Instance 1:
The peak of the given binary tree is 2 and the utmost variety of nodes in that tree is n= 2h+1-1 = 22+1-1 = 23-1 = 7.
Therefore we are able to conclude it’s an ideal binary tree.
Now for an entire binary tree, It’s full as much as top h-1 i.e.; 1, and the final stage parts are saved in left to proper order. Therefore it’s a full Binary tree additionally. Right here is the illustration of parts when saved in an array
Within the array, all the weather are saved repeatedly.
Instance 2:
Peak of the given binary tree is 2 and the utmost variety of nodes that ought to be there are 2h+1 – 1 = 22+1 – 1 = 23 – 1 = 7.
However the variety of nodes within the tree is 6. Therefore it’s not an ideal binary tree.
Now for an entire binary tree, It’s full as much as top h-1 i.e.; 1, and the final stage ingredient are saved in left to proper order. Therefore this can be a full binary tree. Retailer the ingredient in an array and it will likely be like;
Instance 3:
The peak of the binary tree is 2 and the utmost variety of nodes that may be there may be 7, however there are solely 5 nodes therefore it’s not an ideal binary tree.
In case of a whole binary tree, we see that within the final stage parts should not crammed from left to proper order. So it’s not a whole binary tree.
The weather within the array should not steady.
Full Binary Tree vs Full Binary tree:
For a full binary tree, each node has both 2 kids or 0 kids.
Instance 1:
Within the given binary tree there isn’t a node having diploma 1, both 2 or 0 kids for each node, therefore it’s a full binary tree.
For a whole binary tree, parts are saved in stage by stage and never from the leftmost aspect within the final stage. Therefore that is not a whole binary tree. The array illustration is:
Instance 2:
Within the given binary tree there isn’t a node having diploma 1. Each node has a level of both 2 or 0. Therefore it’s a full binary tree.
For a whole binary tree, parts are saved in a stage by stage method and crammed from the leftmost aspect of the final stage. Therefore this a full binary tree. Under is the array illustration of the tree:
Instance 3:
Within the given binary tree node B has diploma 1 which violates the property of full binary tree therefore it’s not a full Binary tree
For a whole binary tree, parts are saved in stage by stage method and crammed from the leftmost aspect of the final stage. Therefore this can be a full binary tree. Array illustration of the binary tree is:
Instance 4:
Within the given binary tree node C has diploma 1 which violates the property of a full binary tree therefore it’s not a full Binary tree
For a whole binary tree, parts are saved in stage by stage method and crammed from the leftmost aspect of the final stage. Right here node E violates the situation. Therefore that is not a whole binary tree.
Creation of Full Binary Tree:
We all know a full binary tree is a tree during which apart from the final stage (say l)all the opposite stage has (2l) nodes and the nodes are lined up from left to proper aspect.
It may be represented utilizing an array. If the mum or dad is it index i so the left little one is at 2i+1 and the proper little one is at 2i+2.
Algorithm:
For the creation of a Full Binary Tree, we require a queue information construction to maintain observe of the inserted nodes.
Step 1: Initialize the foundation with a brand new node when the tree is empty.
Step 2: If the tree is just not empty then get the entrance ingredient
Step 3: If the node has each the youngsters then pop it from the queue.
Step 4: Enqueue the brand new information.
Illustration:
Think about the under array:
1. The first ingredient will the foundation (worth at index = 0)
2. The following ingredient (at index = 1) can be left and third ingredient (index = 2) can be proper little one of root
3. fourth (index = 3) and fifth ingredient (index = 4) would be the left and proper little one of B node
4. Subsequent ingredient (index = 5) can be left little one of the node D
That is how full binary tree is created.
Implementation: For the implementation of constructing a Full Binary Tree from stage order traversal is given in this publish.
Utility of the Full binary tree:
Test if a given binary tree is full or not: Comply with this publish to test if the given binary tree is full or not.
