In this post, we will see 5 SOLID Principles in Java. Robert C. Martin gave five objected oriented design principles, and the acronym S.O.L.I.D is used for it. Each letter of this acronym talks about principles in Java. When you use all the principles of S.O.L.I.D in a combined manner, it becomes easier for you […]

In this post, we will see about Topological Sorting in the graph. Topological Sorting is ordering of vertices or nodes such if there is an edge between (u,v) then u should come before v in topological sorting. Topological sort is possible only for Directed Acyclic Graph(DAG). If there is a cycle in graph, then there […]
