Enqueue and deque in C# Queue class

The queue collection class is a concept in C# and is included in the System.Collection namespace. Elements are stored in a FIFO queue. The first element added will be the first one out, like people queuing up outside a movie theater to buy tickets.

It has two methods.

• Enqueue() method adds value
• Dequeue() method for retrieving values
