DATA STRUCTURESALGORITHMS
What is a Linked List? A linked list is a linear data structure that consists of a series of nodes connected by pointers (in C or C++) or references (in Java, Python and JavaScript). Each node contains data and a pointer/reference to the next node in the list. Unlike arrays, linked lists allow for efficient insertion or removal of elements from any position in the list, as the nodes are not stored contiguously in memory.
What is Queue in Data Structures? A queue is a linear data structure that follows the First-In-First-Out (FIFO) principle. It operates like a line where elements are added at one end (rear) and removed from the other end (front).
What is Stack Data Structure? A stack is a linear data structure that follows the Last-In-First-Out (LIFO) principle. It behaves like a stack of plates, where the last plate added is the first one to be removed.
