What is a Queue?
Queue Data Structure is a collection of elements that implements the FIFO principle, First In First Out. Its main actions are enqueued to insert an element, dequeue to remove, and peek(sometimes referred to as peep) to look at the top element.
It is a linear data structure and also an abstract data type. That means that the elements are placed linearly one after another and that it is defined by their behavior rather than being a mathematical model.
