FAQs

Question: What is the time complexity for searching an element in an array?
Answer: The time complexity for searching an element in an unsorted array is O(n), while for a sorted array, it can be O(log n) using binary search.

Question: How does a doubly linked list differ from a singly linked list?
Answer: A doubly linked list has two pointers for each node, allowing traversal in both directions, whereas a singly linked list only allows traversal in one direction.
