Algorithm

Before starting with the difference among their types, you need to know what sorting is and why it is required. Sorting is the process of arranging items according to particular criteria. It arranges the items in sequence. It helps in grouping and categorizing items with identical properties. We often use the sort option while searching […]

Introduction To Algorithms Before we dive into the interview algorithms, it is essential to understand what algorithms are. An Algorithm is a “set of rules to obtain the expected output from an input”. Algorithms play an important role in problem-solving in general, which is one of the reasons coding interviews are mostly wrapped around algorithms […]

Topological sorting is a linear ordering carried out on directed acyclic graphs (DAG) in which a node or vertex v is visited only after all its dependent vertices are visited, that is, for every directed edge for vertex v to vertex u, v comes before u in the linear ordering. This is only able to be done if the graph is directed […]
