1 3 6
SOLUTION 1
def insert(self, val):
new_node = Node(val)
if self.root is None:
self.root = new_node
return self.root
curr = self.root
while True:
if new_node.info < curr.info:
if curr.left is None:
curr.left = new_node
break
else:
curr = curr.left
elif new_node.info > curr.info:
if curr.right is None:
curr.right = new_node
break
else:
curr = curr.right
return self.root
