A binary tree is a tree data structure in which each node has at most two children, referred to as the left child and the right child.
Solution Code
Data Structures
class Node:
def __init__(self, key):
self.left = None
self.right = None
self.val = key
def insert(self, key):
if self.val is None:
self.val = key
elif key < self.val:
if self.left is None:
self.left = Node(key)
else:
self.left.insert(key)
else:
if self.right is None:
self.right = Node(key)
else:
self.right.insert(key)
# Example usage
root = Node(10)
root.insert(6)
root.insert(14)
root.insert(3)Explanation
