WebSep 1, 2024 · What is a Binary Search Tree? A binary search tree is a binary tree data structure with the following properties. There are no duplicate elements in a binary search tree. The element at the left child of a node is always less than the element at the current node. The left subtree of a node has all elements less than the current node. WebGiven a binary tree, write an iterative and recursive solution to traverse the tree using inorder traversal in C++, Java, and Python. Unlike linked lists, one-dimensional arrays, and other linear data structures, which are traversed in linear order, trees can be traversed in multiple ways in depth–first order (preorder, inorder, and postorder) or breadth–first order …
