Stacks and Queues
by Anonymous
Push and pop the same items in a stack and a queue to see why one reverses the order while the other keeps it.
About this app
Stacks and Queues is an interactive coding-basics lesson that demonstrates how the same items come out in different orders depending on the data structure. Experiment with stack operations to learn last-in, first-out behavior and queue operations to learn first-in, first-out behavior. Guided challenges also connect these ideas to print jobs, undo actions, ride lines, and matching brackets.
