WebDec 13, 2009 · Here is a Python gist which prints the tree by level. The idea behind it is to use BFS and keep a level marker integer which marks the end the last node of the level. This is similar to Naresh's sentinel approach, but without the need of inserting a sentinel inside the queue, since this is accomplished by the level marker.
