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 element you are looking for. This makes random access inefficient in linked lists.
-
Therefore, if you need to store elements with fixed indices where random access is important, an array or an array-based data structure would be a better choice than
