Level order traversal of a Binary Tree

Given a binary tree, we are supposed to traverse the tree using the level order traversal. Level order traversal is just another word for the Breadth First Traversal i.e. traverse the tree level-by-level. Contrary to Depth First Traversal, where we traverse deeper into the tree, level order traversal (or breadth first traversal or breadth first search) traverses every node in a level before going into the next level. The search tree is broadened on each level before going into another level.
