Linked lists with recursions - United States Naval Academy
NettetLinked lists serve a variety of purposes in the real world. They can be used to implement ( spoiler alert!) queues or stacks as well as graphs. They’re also useful for much more complex tasks, such as lifecycle management for an operating system application. Queues or Stacks Queues and stacks differ only in the way elements are retrieved. NettetRecursive Algorithms on Linked Lists The recursive algorithms depend on a series of method calls to chain along the list, rather than an explicit for or while loop. The recursive versions of most linked-list algorithms are quite concise and elegant, compared with their iterative counterparts, as most of the special cases are eliminated. NettetIn a linked list, adding data to the beginning is extremely simple and efficient. You just need to tell the new piece of data to point to the head, and then assign that piece of data to be the new head. No re-indexing required.
