WebAug 19, 2024 · Implement the BSTIterator class that represents an iterator over the in-order traversal of a binary search tree (BST): BSTIterator(TreeNode root) Initializes an object of the BSTIterator class.The root of the BST is given as part of the constructor.The pointer should be initialized to a non-existent number smaller than any element in the BST. WebAssume that the iterator is initialized to the beginning of the list: [1, 2, 3]. Call next () gets you 1, the first element in the list. Now you call peek () and it returns 2, the next element. Calling next () after that still return 2. You call next () the final time and it returns 3, the last element. Calling hasNext () after that should ...
