What are real world examples of when Linked Lists should be used?



Another programmer was mentioning that they haven’t found a use case for using a linked list data structure in any professional software in his career. I couldn’t think of any good examples off the top of my head. He is mostly a C# and Java developer

Can anyone give some examples where this was the correct data structure to solve a particular real world problem?

Answer

A real-world example would be a FIFO queue. An simple array-based list is pretty bad for that because you need to add at one end and remove at the other end, and one of those operations will be O(n) with an array-based list (unless you add extra logic to work with a start AND end index), while both are O(1) with a linked list without extra effort.
