Question

NO ANSWERS FROM GOOGLE Write a program that reads the preorder and inorder traversals of a binary tree, constructs an internal linked representation of the tree, and then outputs the corresponding postorder traversal. You must implement your own binary tree node and tree classes . However, you only need to implement the methods that are required to provide the desired output. At least one of your methods must be implemented using recursion. DO NOT GIVE ME GOOGLE ANSWERS PLEASE

input: DBACEGF

ABCDEFG (The program should read from the standard input two lines. The first line contains a string representing the preorder traversal of a binary tree, and the second contains a string representing the inorder traversal of the same tree. Nodes of the tree are identified by unique capital letters. )

output: ACBFGED

(Your program must print a string representing the postorder traversal of the tree followed by a newline character.)

Explanation / Answer

Please rate with 5 stars :)

Let us consider the below traversals:

Inorder sequence: D B E A F C
Preorder sequence: A B D E C F

In a Preorder sequence, leftmost element is the root of the tree. So we know
