tree is also a binary tree that is organized and has structurally organized nodes. every subtree must be a part of the concerned structure. performance of operations you can perform operations like insertion, deletion, and traversal using the binary tree. since these are sorted types of binary ...

In order traversal using stack In order to reduce memory from O(N) to O(lgN), aka O(h) where h is the height of the tree, an alternative is return the next() inline while we are performing the recursion. The tricky part is if we still perform the in-order traversal using recursion...
因为是Binary Search Tree, 所以要用inorder travesal,所以可以在初始化的时候将tree 转变为stack,并且用一个指针来指向现在的node所在的位置,如果超过stack,那么就没有next。 T: O(n), S: O(n) Code: #Definition for a binary tree node.#class TreeNode(object):#def __init__(self, x):#self.val...

Post order traversal using recursion Calculate the height of the left subtree, calculate the height of the right subtree, then compare. If it's already not balanced, return -1 and directly return Time Complexity: O(N), N is the total tree nodes since it is visited once and only once ...
