I’m a third year engineering student preparing for placements but got stuck in data structures and algorithms subject. Can someone help me understand the difference between Linked list, stack and queue data structures? I’m having a hard time understanding the implementation and time complexities of various operations on these data structures.
Linked list, stack and queue are all linear data structures that store elements in a linear fashion. The main difference lies in the way they insert and delete elements. A linked list allows insertion and deletion at any position, while a stack allows insertion and deletion at one end (top) only, and a queue allows insertion at one end (rear) and deletion at another end (front).
The time complexity of various operations also differs. For example, insertion and deletion operations in a linked list are O(1), while in a stack and queue they depend on the underlying implementation – array or linked list. Hope this helps clear the basic differences! Let me know if you have any other questions.
