What is the difference between a perfectly balanced binary tree and a complete binary tree?

A balanced binary tree is the binary tree where the depth of the two subtrees of every node never differ by more than 1. A complete binary tree is a binary tree whose all levels except the last level are completely filled and all the leaves in the last level are all to the left side.

What do you mean by binary tree almost complete binary tree and complete binary tree?

Strictly binary trees are binary trees where every node either has two children or is a leaf (has no children). Complete binary trees are strictly binary trees where every leaf is on the same “maximum” level. Almost complete binary trees are not necessarily strictly binary (although they can be), and are not complete.

What is the difference between tree and binary tree?

The main difference between tree and binary tree is that tree arranges data in a structure similar to a tree, in a hierarchical manner, while a binary tree is a type of tree in which a parent node can have a maximum of two child nodes.

Is a full binary tree is also a complete binary tree?

Every binary tree is either complete or full. Every full binary tree is also a complete binary tree.

Is a perfect tree a full tree?

Strictly speaking a Perfect Binary Tree is one where every node in all of the levels are filled. There are no gaps. But a Complete tree doesn’t have such restriction, its last level just needs to be filled from the left. Unfortunately some use the two names to mean the same thing, interchangeably.

What is full binary tree?

A full binary tree is also known as 2-tree in which every node other than the leaf nodes has two child nodes. It means all the leaf nodes should be at the same level and all other internal nodes should contain two child nodes each.

What is a complete tree?

A complete binary tree is a binary tree where nodes are filled in from left to right. In a complete binary tree: Every level except the last one is full.

What is a complete binary tree Mcq?

Explanation: A binary tree, which is completely filled, with the possible exception of the bottom level, which is filled from left to right is called complete binary tree. A Tree in which each node has exactly zero or two children is called full binary tree.

Is a full tree complete?

Definition: a binary tree T is full if each node is either a leaf or possesses exactly two child nodes. Definition: a binary tree T with n levels is complete if all levels except possibly the last are completely full, and the last level has all its nodes to the left side. Full but not complete.

What makes a complete binary tree?

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. All the leaf elements must lean towards the left. The last leaf element might not have a right sibling i.e. a complete binary tree doesn’t have to be a full binary tree.
