Linked Lists, Queues, Stacks

VisuAlgo: Linked Lists, Queues, Stacks

Linked Lists (single and doubly linked), stacks, and queues are explained on this page from Visu Algo. The site is more than a simple animation of the data structures - it allows students to interact and perform different operations (insert, remove, find, etc), then displays the pseudo-code to achieve the result while showing an animation of the data structure.
