How is a doubly linked list different from a singly linked list in terms of memory usage?Doubly linked list uses less memory.Doubly linked list uses more memory.Both use the same amount of memory.Memory usage depends on the size of the list.
Solution
A doubly linked list uses more memory than a singly linked list. Here's why:
-
In a singly linked list, each node contains data and a reference (or link) to the next node in the sequence. This means for each node, we need space for the data and one pointer.
-
In a doubly linked list, each node contains data and two references (or links) to both the next and the previous node in the sequence. This means for each node, we need space for the data and two pointers.
-
Therefore, a doubly linked list requires more memory for the storage of the extra pointers for each node.
-
The exact memory usage does indeed depend on the size of the list - the more nodes in the list, the more memory required. However, for any given size, a doubly linked list will always use more memory than a singly linked list due to the additional pointers.
