A group of related data elements stored at adjacent memory locations is referred to as an array. One of the most basic data structures, it allows for random access to each data element by its index number. Properties of an Array: Arrays contain a number of crucial characteristics that make them helpful in a wide […]

What is Time Complexity? Time complexity is a key concept in computer science, particularly in data structures and algorithms(DSA). It measures how long it takes to run an algorithm or complete a task, and it is usually expressed in terms of the input size. What Is Space Complexity? Space complexity is a measure of the […]

Singly Linked List Singly Linked List is a linear and connected data structure made of Nodes. Each node is composed of a variable data where its content (actual value) is stored and a pointer to the next Node (next node location) on the list. The Linked List has a pointer to the first element of this Node […]
