Chapter 21, Problem 13RQE

Explanation of Solution

Pseudocode algorithm for in-order traversal of a binary tree:

In-order Traversal:

In the in-order traversal, initially it traverses the left sub tree, the visits the root node, and then traverses the right sub tree

Pseudocode:

In this algorithm, recursion of binary tree “T” is “T’”, let us consider “N” denote the root of a subtree of “T’”, “L” is the subtree of “T’” whose root is the left child of “N”, and “R” be the subtree of “T’” whose root is the right child of “N”...
