Linked Lists What Is Linked List? A linked list is a data structure that stores elements, or nodes, in a linear order. Nodes in a linked list, have both data and only one pointer to the next node. They are called as singly linked lists. In some linked lists, nodes also have another pointer to […]

What Is Time Complexity? Time complexity, or Big O notation, is one way describing how the time it takes to execute your function grows as the size of the input increases. In other words, this is a simplified analysis of an algorithm’s efficiency; it is independent from the machine algorithms run on because it only […]
