Print Postorder traversal from given Inorder and Preorder traversals

Given Inorder and Preorder traversals of a binary tree, print Postorder traversal.

Example:

Input:
Inorder traversal in[] = {4, 2, 5, 1, 3, 6}
Preorder traversal pre[] = {1, 2, 4, 5, 3, 6}

Output:
Postorder traversal is {4, 5, 2, 6, 3, 1}
