Queue in data structure: What is Queue in

What is Queue in Data Structure? A Queue Data Structure is a linear structure that stores elements in First In First Out (FIFO) order . It supports basic queue operations like enqueue() (insert), dequeue() (remove), and peek() (view front element). Queue is a linear data structure that follows FIFO (First In First Out) Principle, so the first element inserted is the first to be popped out. FIFO Principle in Queue : FIFO Principle states that the first element added to the Queue will be the first one to be removed or processed. So, Queue is like a line of people waiting to purchase tickets, where the first person in line is the first person served. (i.e. First Come First Serve). Basic Terminologies of Queue Front: Position of the entry ... Let’s learn everything about queues , how they operate within data structures , and their practical applications. What is Queue in Data Structure ? A queue in data structures is a linear collection of elements that operates under the First In, First Out (FIFO) principle. Queue is a widely used linear, non-primitive data structure that models real-world scenarios where data must be processed in the same order in which it arrives. A queue is an ordered list in which insertion is done at one end called REAR and deletion at another end called FRONT.
