Level Order Traversal of Binary Tree
A Quick Overview
Given a binary tree, the task is to print level order traversal line by line of the tree. But what is level order traversal?
Problem Statement
Learn through example
This approach has two functions. One prints all nodes at a particular level (CurrentLevel), and another prints level order traversal (Levelorder).
Recursive Approach
Check its implementation
Time complexity:
O(n^2) (for skewed tree)
Space complexity:
O(n) O(n^2) (for skewed tree)
Space complexity:
O(log n) (for balanced tree)

1. Initially, we insert root into queue and iterate over it until it is empty.
2. We will pop from top of queue in every iteration & print value at the top.
