Construct Tree Using Inorder and Preorder
Given Preorder and Inorder traversal of a binary tree, create
the binary tree associated with the traversals.You just need to
construct the tree and return the root.
Note: Assume binary tree contains only unique elements.
Input format :
Line 1 : n (Total number of nodes in binary tree)
Line 2 : Pre order traversal
Line 3 : Inorder Traversal
Output Format :
Elements are printed level wise, each level in new line...
