Dont use others answers! will rate! THANK YOU! Although you can uniquely construct a binary tree from either its preorder and inorder traversals or its postorder and inorder traversals, more than one binary tree can have the same preorder traversal and the same postorder traversal. Draw two different binary trees in the SIMPLEST case with the same preorder and postorder traversals.
The height of a tree is equal to the number of its nodes, thus how many nodes can there be in a binary tree that is 5 levels tall if a 1-node tree has a height of 1?
