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:
