   How to implement queue in Python?

   • Queue in Python can be implemented using deque class from the collections module. Deque is preferred over list in the cases where we need quicker append and pop operations from both the ends of container, as deque provides an O (1) time complexity for append and pop operations as compared to list which provides O (n) time complexity.

   What is a queue in data structure?

   • Like a stack, the queue is a linear data structure that stores items in a First In First Out (FIFO) manner. With a queue, the least recently added item is removed first. A good example of a queue is any queue of consumers for a resource where the consumer that came first is served first. Operations associated with queue are:

   What is an example of a queue?

   • With a queue, the least recently added item is removed first. A good example of a queue is any queue of consumers for a resource where the consumer that came first is served first. Operations associated with queue are: Enqueue: Adds an item to the queue. If the queue is full, then it is said to be an Overflow condition – Time Complexity : O (1)

   What is LinkedList class?

   • The LinkedList class is an implementation of the LinkedList data structure which is a linear data structure where the elements are not stored in contiguous locations and every element is a separate object with a data part and address part. The elements are linked using pointers and addresses. Each element is known as a node.

   2 days ago · While an ArrayList uses a normal array to store elements, a LinkedList uses a doubly linked list to store elements. It implements both the List and Queue interfaces. Each element inside a LinkedList is called a node. A node holds the data and a reference to the next element in the list.
