Question
python: In a binary search tree, write another way of function that takes in a root, p, and checks whether the tree rooted in p is a binary search tree or not. What is the time complexity of your function?
def is_bst(self, p):
root=p
def helper(root, l, r):
if not root:
return True
if not (left<root.val and root.val<right):
return False
return helper(root.l, l, root.val) and helper(root.r, root.val, r)
return helper(root, float('-inf'), float('inf'))
