Questions and Answers

Which of the following statements is true about linked lists?

Linked lists allow for efficient insertion or removal of elements at any position. (correct)

Each element in a linked list points to the previous element.

Linked lists can only be traversed in a forward direction.

Linked lists store data elements in a random order in memory.

What is the main advantage of using linked lists?

Linked lists can store data elements in a contiguous block of memory.

Linked lists have a fixed size and cannot be resized.

Linked lists provide faster access to data compared to arrays. (correct)

Linked lists allow for random access to elements.

What is a drawback of using linked lists?

Linked lists have a higher memory overhead compared to arrays. (correct)

Linked lists can only store a limited number of elements.

Study Notes

Linked Lists

One of the true statements about linked lists is that they can dynamically allocate and deallocate memory as elements are added or removed.

Advantages of Linked Lists

The main advantage of using linked lists is that they can efficiently insert or delete elements at any position in the list, with a time complexity of O(1).

Drawbacks of Linked Lists

A drawback of using linked lists is that they have a slower search time compared to arrays, with a time complexity of O(n), because each element must be traversed in sequence to find a specific element.
Another drawback is that they require more memory than arrays, because each element must store a pointer to the next element in the list.
