Python Day 22: Binary Search Trees
The height of a binary search tree is the number of edges between the tree's root and its furthest leaf. You are given a pointer, root, pointing to the root of a binary search tree. Complete the getHeight function provided in your editor so that it returns the height of the binary search tree.
- class Node:
- def __init__(self,data):
- self.right=self.left=None
- self.data = data
- class Solution:
- def insert(self,root,data):
- if root==None:
- return Node(data)
- else:
- if data<=root.data:
- cur=self.insert(root.left,data)
- root.left=cur
- else:
- cur=self.insert(root.right,data)
- root.right=cur
- return root

- def getHeight(self,root):
- if root:
- leftDepth = self.getHeight(root.left)
- rightDepth = self.getHeight(root.right)
-
- if leftDepth > rightDepth:
- return leftDepth + 1
- else:
- return rightDepth + 1
- else:
- return -1
