Stacks and queues are fundamental data structures used in computer science. They organize data to allow efficient access and modification. Understanding their operations is essential for designing effective algorithms and software systems.
Stack Operations
A stack follows the Last In, First Out (LIFO) principle. The primary operations are push, pop, and peek.
The push operation adds an element to the top of the stack. The pop removes the top element, and peek allows viewing the top element without removing it.
Queue Operations
A queue operates on the First In, First Out (FIFO) principle. Its main operations include enqueue and dequeue.
The enqueue operation adds an element to the rear of the queue, while dequeue removes the element from the front. These operations maintain the order of data processing.
Practical Applications
Stacks are used in function call management, undo mechanisms, and syntax parsing. Queues are common in scheduling, buffering data, and managing print jobs.
