In which cases is it preferable to use the LinkedList data structure instead of other collections?

LinkedList is preferred when you need to frequently perform insertions and deletions of elements in the middle of the list, especially if the performance of these operations is important. Unlike ArrayList (or an array), where inserting or deleting in the middle requires shifting elements, in LinkedList these operations are faster because it is enough to reassign the node links.

However, access to elements by index in LinkedList is slower than in an array, as it requires traversing the nodes sequentially.

Examples of use cases for LinkedList:

• Implementation of queues and stacks with frequent insertions and deletions.
• When the size of the collection is unknown in advance and a dynamic structure is important.
• For implementing navigation forward and backward through elements (doubly linked list).
