Reconstructing Binary Trees Via Traversals Recall the binary tree data structure; recall three algorithms for traversing the tree: the inorder traversal, the preorder traversal, and the postorder traversal. Suppose you are given the preorder traversal and the inorder traversal of a binary tree. Can you reconstruct the tree? If so, give an algorithm for doing so and prove its correctness. If not, give a counter example. Note that a binary tree is not necessarily a binary search tree. Suppose you are given the preorder and postorder traversals of a binary tree. Can you reconstruct the tree? If so, give an algorithm for doing so and prove its correctness If not, give a counter example. Suppose you are given the preorder traversal of a binary tree. In addition, you are told that the tree is a binary search tree. Can you reconstruct the tree? If so, give an algorithm for doing so and prove its correctness. If not, give a counter example.

yes
me can reconstruct the tree.
Algorithm: build Treet)
1. pick an element boom prender. Incremento preorder
Index Vanable to pick next element in nest recursive
call.
2. create a new tree node...
