What are the advantages and disadvantages of array over linked list?
Question
What are the advantages and disadvantages of array over linked list?
Solution 1
Advantages of Array over Linked List:
-
Random Access: Arrays allow random access of elements. This makes accessing elements by position faster.
-
Less Memory: With arrays, there is no extra memory needed to store next and previous references.
-
Easy to use: Arrays are simple and easy to use. They can be used to implement multiple data structures like stacks, queues, heaps, etc.
Disadvantages of Array over Linked List:
-
Fixed Size: The size of the array is static (needs to be defined at the time of allocation). This can cause wastage of memory if the array is not fully utilized.
-
Insertion and Deletion: Inserting and deleting elements can be costly since the room has to be made for the new elements and to delete an element, shifting operation is required.
Advantages of Linked List over Array:
-
Dynamic Size: The size of the linked list is dynamic and can grow and shrink during the execution of the program.
-
Insertion and Deletion: Insertion and deletion of nodes are really easier. No shifting operation is required.
Disadvantages of Linked List over Array:
-
Random Access: Random access is not allowed. We have to access elements sequentially starting from the first node. So we cannot do a binary search with linked lists.
-
More Memory: Each element of the linked list requires extra memory for a pointer to the next element in addition to its own data.
