N-ary Tree Level Order Traversal 🎯

Welcome to the exciting world of N-ary Trees! In this lesson, we'll dive deep into N-ary Tree Level Order Traversal. By the end of it, you'll be able to navigate through N-ary trees like a pro!

What is an N-ary Tree? 📝

An N-ary Tree is a tree in which each node can have more than two children. Unlike Binary Trees, N-ary Trees can be used to model more complex real-world structures.

💡 Pro Tip: N-ary Tree is also known as Multiway Tree or Polytree.

Level Order Traversal 💡

Level Order Traversal is a way to traverse a tree where we visit nodes at the same level in each iteration. It's like moving from one level to another, visiting each node at the current level before moving to the next.

Level Order Traversal in N-ary Tree 💡

Level Order Traversal in N-ary Tree works in a similar way as in Binary Trees, but with a twist. Since nodes can have more than two children, we need to keep track of all branches at the same level.

N-ary Tree Level Order Traversal Algorithm 💡

Start from the root node.
Enqueue the root node.
While the queue is not empty:
- Dequeue a node.
- Print the data of the dequeued node.
- Enqueue all its children (if any).
Repeat step 3 until the queue is empty.

Python Example 💡

Here's a simple Python example to illustrate N-ary Tree Level Order Traversal.

python

class Node:
    def __init__(self, data):
        self.data = data
        self.children = []

def levelOrder(root):
    if root is None:
        return

    queue = [root]
    while queue:
        current_node = queue.pop(0)
        print(current_node.data, end=" ")
        queue.extend(current_node.children)

# Creating a simple N-ary Tree
root = Node(1)
root.children = [Node(2), Node(3), Node(4)]
root.children[0].children = [Node(5), Node(6)]
root.children[1].children = [Node(7), Node(8)]
root.children[2].children = [Node(9), Node(10)]

levelOrder(root)

Output: 1 2 3 4 5 6 7 8 9 10
