How do you make a onstruct binary tree from preorder and inorder traversal?
Given two integer arrays preorder and inorder where preorder is the preorder traversal of a binary tree and inorder is the inorder traversal of the same tree, construct and return the binary tree.

Answers

Answer 1

Here is a step-by-step algorithm to construct a binary tree from its preorder and inorder traversals:

Start with the first element of the preorder array, which is the root of the tree.Find the root in the inorder array. Recursively construct the left subtree by calling the same algorithm on the elements of the left subtree, using the portion of the preorder array that corresponds to the left subtree.Recursively construct the right subtree by calling the same algorithm on the elements of the right subtree, using the portion of the preorder array that corresponds to the right subtree.Return the root node of the constructed tree.

It's a divide and conquer approach where we start from the root of the tree and keep on dividing the tree in left and right subtree. The preorder array will give us the root element first and inorder array will give us the elements in left and right subtree. The elements to the left of the root in the inorder array are the left subtree, and the elements to the right of the root are the right subtree.
