FAQs

Question: What is the time complexity of inserting an element in a linked list?
Answer: The time complexity for inserting an element in a linked list is O(1) if the position is known, otherwise it is O(n).

Question: How do arrays differ from linked lists in terms of memory allocation?
Answer: Arrays use contiguous memory allocation, while linked lists use non-contiguous memory allocation, allowing for dynamic resizing.
