Topics in Queue
Introduction to Queue and FIFO Principle
- Queue is an ordered linear list with different ends for insertion and deletion
- FIFO (First-In-First-Out) principle: first element inserted is first to be removed
- REAR/TAIL: end where new elements are added (enqueue operation)
Queue Operations and Implementation
- ENQUEUE: Insert element at rear using append() method
- DEQUEUE: Remove element from front using pop(0) method
- ISEMPTY: Check if queue has elements using len() == 0
Python Implementation of Queue Functions
- Create queue: myQueue = list()
- Function structure: def function_name(myQueue, parameters)
- Error handling using isEmpty() check before operations
Introduction to Deque (Double-ended Queue)
- Deque allows insertion and deletion from both ends (front and rear)
- Can implement both stack and queue using deque
- More flexible than regular queue or stack
