Question
When designing a system where data records are
frequently added and removed from the middle of a sequence, which data structure offers the most efficient operations for these specific tasks?Solution
Linked lists excel at insertions and deletions, especially in the middle, as they only require updating a few pointers (O(1) after finding the position, O(n) for finding the position). Arrays, in contrast, would require shifting many elements (O(n)).
