The binary search tree is the data structure used to maintain a sorted orderly list of elements. In this tree, each node can have a maximum of only two children. The format followed while storing the values is that the left node of the main node should have a smaller value than the mai...

Example Now let’s see the example of a binary tree in a data structure as follows. class B_Node: def __init__(self, key_value): self.left_B = None self.right_B = None self.val_B = key_value def PreOrder_B(self): print(self.val_B, end=' ') ...
The time complexity of search and insert rely on the height of the tree. On average, binary search trees with n nodes haveO(log n)height. However in the worst case the tree can have a height ofO(n)when the unbalanced tree resembles a linked list. For example in this case : ...

二叉搜索树(Binary Search Tree,简称BST)也称为二叉查找树、有序二叉树(Ordered Binary Tree),或排序二叉树(Sorted Binary Tree)。二叉搜索树是一颗空树,或具有以下性质的二叉树: 如果任意节点的左子树不为空,则左子树上所有节点的值小于它的根节点的值。
