1
/ \
2 3
/ \
4 5
The following tree should output 1, 2, 3, 4, 5.
class Node:
def __init__(self, val, left=None, right=None):
self.val = val
self.left = left
self.right = right
def print_level_order(root):
# Fill this in.
root = Node(1, Node(2), Node(3, Node(4), Node(5)))
print_level_order(root)
# 1 2 3 4 5
