Implement an iterator over a binary search tree (BST). Your iterator will be initialized with the root node of a BST. 实现一个适用于二叉查找树的迭代器,该迭代器通过二叉查找树的根结点来实例化。 Calling next() will return the next sm... ...
Given the root node of a binary search tree (BST) and a value to be inserted into the tree, insert the value into the BST. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Note that there may exist multipl...
基于排名的BST函数insert()和split()是指在二叉搜索树(Binary Search Tree)中,根据节点的排名来进行插入和分割操作。 insert()函数的实现: 首先,需要确定要插入的节点的排名。排名是指节点在二叉搜索树中按照某种顺序(如升序)的位置。 然后,从根节点开始,比较要插入节点的排名与当前节点的排名。
Given the root node of a binary search tree (BST) and a value to be inserted into the tree, insert the value into the BST. Return the root node of the BST after the insertion. It is guaranteed that the new value does not exist in the original BST. Note that there may exist multipl...

I've been stuck on the insertion part of the binary search tree. I get so confused with nested structs. The basic idea of this program is to create a bst that is able to hold names and double values which get stored by value (obviously). ...
