Construct Binary Tree from Inorder and Postorder TraversalGiven inorder and postorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree.
Construct Binary Tree from Preorder and Inorder TraversalGiven preorder and inorder traversal of a tree, construct the binary tree. Note: You may assume that duplicates do not exist in the tree. 提
Binary Tree Zigzag Level Order TraversalGiven a binary tree, return the zigzag level order traversal of its nodes’ values. (ie, from left to right, then right to left for the next level and alternate
Validate Binary Search TreeGiven a binary tree, determine if it is a valid binary search tree (BST). Assume a BST is defined as follows: The left subtree of a node contains only nodes with keys less
Unique Binary Search Trees IIGiven an integer n, generate all structurally unique BST’s (binary search trees) that store values 1…n. For example:Given n = 3, your program should return all 5 unique B
Unique Binary Search TreesGiven n, how many structurally unique BST’s (binary search trees) that store values 1…n? For example:Given n = 3, there are a total of 5 unique BST’s. 123451 3 3
Binary Tree Inorder TraversalGiven a binary tree, return the inorder traversal of its nodes’ values. For example:Given binary tree [1,null,2,3], 123451 \ 2 /3 return [1,3,2]. Note: Recursive solutio
