Explain the implementation of a level-order traversal of a tree.
What will be an ideal response?
The implementation of a level-order traversal of a tree involves a queue data structure. The main part of the
algorithm dequeues a node from the queue, enqueues its left and right child, and then visits the node. The first step of the
algorithm enqueues the root, and it continues until the queue is empty.

No matter how complicated a program is or looks it can all be broken down into a series of 0’s and 1’s. 4. A field is a random group of characters. 5. To distinguish records, there has to be one field that’s unique for each instance; this is called the record key.
