Answer / Shruti Agarwal
The main differences between LinkedList and ArrayList are:
1. Implementation: ArrayList uses an array to store elements, while LinkedList uses a chain of nodes.
2. Efficiency of Access: ArrayList provides fast access to elements at specific indexes due to its underlying array structure, whereas LinkedList requires traversal through the linked nodes for similar operations.
3. Insertion and Deletion Efficiency: Insertions and deletions are more efficient in LinkedList as it only needs to adjust pointers (rather than shifting all subsequent elements), while ArrayList requires rearranging elements upon insertion or deletion.
