Hey, Why is the binary tree uniquely determined when both the in-order, post-order and pre-order arrangements are given values.    In other words:   i) Show that if both the inorder and the postorder order are given for a binary tree with unique values, the binary tree is uniquely determined.   ii) Show that for a given postorder arrangement binary search trees are unique
