Level order traversal of Binary Tree | Step by step demo with example | Study Algorithms

When you look at a binary tree, the first thing you might see is that each node is at a different height. This simply implies that you can traverse the tree level by level as well. For each level you go left to right, hence the element that is seen first should be processed first. Given this information we can take the help of a queue data structure to perform a level order traversal of binary tree. Watch this video to see a step by step procedure with a code sample written in JAVA.

[@ionguzun3952]

nice video, can you do more about trees?

[@nikoo28]

Check out my playlist on trees. It has a bunch of stuff

[@nageshnimmala7366]

Do some videos on views of a tree

[@nikoo28]

you mean like a left view and a right view?
