WebAug 1, 2024 · The BFS can be used to determine the level of each node from a given source node. Algorithm: Create the tree, a queue to store the nodes and insert the root or starting node in the queue. Create an extra array level of size v (number of vertices) and create a visited array. Run a loop while size of queue is greater than 0. 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.

WebAug 3, 2024 · To implement BFS we use a queue. For Binary trees, we have Level Order Traversal which follows BFS.
