Code Binary Tree

Convert binary tree to threaded binary tree

A binary tree is a tree data structure in which each node has at most two children, referred to as the left child and the right child. A threaded binary tree is a binary tree in which every node has either a left thread, a right thread, or both. A left thread points to the node's predecessor in an inorder traversal, and a right thread points to the node's successor in an inorder traversal. In other words, a threaded binary tree allows us to traverse the tree in an inorder fashion without using a stack or recursion.

A threaded binary tree is a special type of binary tree whose leaf node null field is connected to the inorder successor and predecessor nodes.

Inorder successor : Next node in inorder sequence.

Inorder predecessor : Previous node in inorder sequence. For example.
