![]() ![]() To remove an object, it can be popped off the top of the stack or shifted off the front of the queue. To add an object to the stack or queue, it can be appended to the end of the array. Here are a few common ways to implement these data structures:Īrrays: Stacks and queues can be implemented using simple arrays, with the top of the stack or the front of the queue being stored at the first index of the array. Stacks and queues can be implemented in several different ways, depending on the specific requirements of the application. For example, a queue can be used to manage the order in which tasks are executed on a computer, with tasks being added to the end of the queue and executed in the order in which they were added. Queues are often used to manage the order in which tasks are executed in a computer or to store data that will be processed in a specific order. This means that the first object added to the queue will be the first one to be removed. ![]() queuesĪ queue is similar to a stack, but objects are stored and accessed according to the first-in, first-out (FIFO) principle. ![]() For example, a stack can be used to track the history of a web browser, with the most recent pages visited being added to the top of the stack. Stacks are often used to track the history of a process or to evaluate expressions in programming languages. This means that the last object added to the stack will be the first one to be removed. A stack is a collection of objects that are stored and accessed according to the last-in, first-out (LIFO) principle. ![]()
