Which of the following is NOT a valid use case for a linked list?Group of answer choicesRepresenting sparse matricesImplementing stacks and queuesStoring elements with fixed indicesMaintaining a sorted list of elements
Solution
Storing elements with fixed indices is NOT a valid use case for a linked list.
Here's why:
-
Linked lists are dynamic data structures. They do not have fixed indices like arrays. In a linked list, elements are linked using pointers and each element can be located at any place in memory.
-
Accessing elements in a linked list is not as straightforward as in an array. In an array, you can directly access any element using its index. However, in a linked list, you have to start from the head and follow the references until you get to the desired element. This makes random access inefficient in linked lists.
-
Therefore, if you need to frequently access elements by their indices, a linked list would not be the best choice. An array or an array-based data structure would be more suitable in this case.
