What is the difference between binary tree and threaded binary tree?

Answer 1

A binary tree is simply a tree in which each node can have at most two children.

A binary search tree is a binary tree in which the nodes are assigned values, with the following restrictions ;

-No duplicate values.

-The left subtree of a node can only have values less than the node

-The right subtree of a node can only have values greater than the node

and recursively defined;

-The left subtree of a node is a binary search tree.

-The right subtree of a node is a binary search tree.

Answer 2

Advantages of a threaded tree compared to an non-threaded one include:

> Faster traversal, since no stack need be maintained

> Less memory usage during traversal, since no stack need be maintained

> Algorithms that require moving forward and backward in the tree during traversal are much simplified, since this library implements only forward movement

> Greater generality, since one can go from a node to its successor or predecessor given only the node; no traversal need be in progress

Some disadvantages of threaded trees are:

> Slower tree creation, since threads need to be maintained. This can partly be alleviated by constructing the tree as an non-threaded tree, then threading it with a special libavl function

> In theory, threaded trees need two extra bits per node to indicate whether each child pointer points to an ordinary node or the node's successor/predecessor node. In libavl, however, these bits are stored in a byte that is used for structure alignment padding in non-threaded binary trees, so no extra storage is used

Answer 3

A tree is a data structure that only allows one parent but multiple children. A binary search tree, however, is a specific case of a tree. First it is a binary tree, meaning that a node can at most have 2 children. And it is a binary search tree, meaning that the child to the left of a parent is less than the parent while the child on the right is greater than the parent. To see an example, follow the link on the bottom.

Answer 4

· The traversal operation is faster than that of its unthreaded version, because with threaded binary tree non-recursive implementation is possible which can run faster and does not require the botheration of stock management. · The second advantage is more subtle with a threaded binary tree; we can efficiently determine the predecessor and successor nodes starting from any node. A stack is required to provide upward pointing information in the tree whereas in a threaded binary tree, without having to incur the overload of using a stack mechanism the same can be carried out with the threads. · Any node can be accessible from any other node. Threads are usually more to upward whereas links are downward. Thus in a threaded tree, one can move in either direction and nodes are in fact circularly linked. This is not possible in unthreaded counter part because there we can move only in downward direction starting form root. · Insertion into and deletions from a threaded tree are all although time consuming operations(since we have to manipulate both links and threads) but these are very easy to implement.

Answer 5

A binary tree is threaded by making all right child pointers that would normally be null point to the inorder successor of the node, and all left child pointers that would normally be null point to the inorder predecessor of the node

Answer 6

A binary tree is a tree data structure where each node can have at most two children, left and right. A threaded binary tree is a binary tree with extra links, called threads, that connect nodes with no children to their inorder successors or predecessors directly, making traversal operations more efficient. The main difference is that a threaded binary tree has additional links to optimize traversal operations.

Answer 7

A tree is a structure where each node contains none, one, or more pointers to child nodes. A binary tree is a tree with at most two pointers to child nodes in each node.
