Breadth-first Search Complexity

The video tutorial explains the time and space complexity of a program using a tree structure. It details how the time complexity is O(N) due to the number of nodes and the use of a single while loop. The space complexity is also O(N) as it involves storing elements in a queue. The tutorial further discusses traversal techniques and how to optimize the process by directly printing results instead of appending them. The explanation aims to provide a clear understanding of these complexities in the context of level order traversal.
