Inorder and preorder traversal to reconstruct a binary tree, Data Structure & Algorithms

Q. Using the following given inorder and preorder traversal reconstruct a binary tree

Inorder sequence is	D, G, B, H, E, A, F, I, C
Preorder sequence is	A, B, D, G, E, H, C, F, I

Ans:

The In-order sequence given to us is :- D, G, B, H, E, A, F, I, C

Pre-order sequence given to us is:- A, B, D, G, E, H, C, F, I

The binary tree T is drawn from its root downward by selecting the first node in its pre-order as root of T then study the left and right child recursively. The tree T is drawn below:
