The Breadth-First search algorithm is a way to traverse through graphs or trees so that the nodes are visited level by level. The depth-first search algorithm, on the other hand, will traverse nodes to the depth-first as its name suggests, in other...
The depth-first-search algorithm is used a lot in algorithms where it’s necessary to traverse through nodes. In day-to-day work, this algorithm is very likely to not be used though. However, LinkedList uses the concepts of graphs. But before...
The tree data structure is a type of graph. A tree has a root node (top node) that will have a relationship with its child nodes. The path that connects the root node to the child nodes is called a branch. The leaf node is the node that...
The graph data structure is a composition of nodes connected by edges. Graphs are vastly used in the real world. One very simple example is Facebook where a person is a friend of another person and so on. Graphs can also represent routes from one...
Recursion is a programming fundamental that is highly used in algorithms. Simply put, recursion is the ability of a method to call itself. When a method calls itself it stacks up and uses the LIFO (Last-in First-out) approach. It’s the same...
Malta is an impressive country to visit in Europe. It’s small but there is a lot of history, beautiful views, and great food, also the people are welcoming there. I will also show you how my experience will help YOU to go to the next level in...
Knowing how constructors work in Java will help you to design a code structure that is flexible and maintainable. In this Java code challenge, you will learn how a constructor behaves when we use inheritance. Do you know what happens when one class...
Did you know that every variable in Java is passed by value and not by reference? However, what happens when we pass an object to a method? Do we manipulate the value or the reference? This is exactly what you will explore in the following Java...
Functional interfaces in Java are crucial to master. In this Java code challenge, we will explore the Supplier and Consumer functional interfaces. Do you know how a lambda behaves in Java? Try to solve this Java code challenge and make sure you know...
Composing functions with lambda might come in handy when you need to execute multiple functions. In the following Java code challenge, we will explore the UnaryOperator, Function, and BiFunction functional interfaces working in a composed way. Can...
