Scala Queue Programs

A queue is a first-in-first-out (FIFO) data structure. In Scala programming language, there are both types of queues immutable and mutable. A mutable queue is a queue that can be updated or extended in place. An immutable queue is a queue that can never change.

The two most basic operations of Queue are,

• Enqueue – Adding an element at the end of the queue.
• Dequeue – Deleting an element from the beginning of the queue.

This section contains solved Scala Queue Programs, practice these Scala programs to learn the concept of Scala queues, these programs contain the solved code, outputs, and the detailed explanation of the statements, functions used in the Scala Queue Programs.
