WebConstruct Binary Search Tree from Preorder Traversal - Given an array of integers preorder, which represents the preorder traversal of a BST (i.e., binary search tree), construct the tree and return its root. It is guaranteed that there is always possible to find a binary search tree with the given requirements for the given test cases. WebNov 16, 2015 · Both have preorder 123, and both have postorder 321, but they’re not the same binary tree. More generally, if a node has only one child, preorder and postorder do not contain enough information to determine whether that child is a left child or a right child.
