Is your feature request related to a problem? Please describe. Given the root of the Binary Tree. The task is to print the Level order traversal of a tree is breadth-first traversal for the tree.

Describe the solution you'd like Level Order Binary Tree Traversal Using Queue For each node, first, the node is visited and then its child nodes are put in a FIFO queue. Then again the first node is popped out and then its child nodes are put in a FIFO queue and repeat until the queue becomes empty.
