Today, the Java Streams API is in extensive use, making Java more functional than ever. Thus, models like MapReduce have emerged for easier stream handling. Although these models made using streams effortless, they've also introduced efficiency concerns. The built-in parallel() operation is simple enough to deploy, and allows you to...
Sorting is one of the fundamental techniques used in solving problems, especially in those related to writing and implementing efficient algorithms. Usually, sorting is paired with searching - meaning we first sort elements in the given collection, then search for something within it, as it is generally easier to search...

Graphs are a convenient way to store certain types of data. The concept was ported from mathematics and appropriated for the needs of computer science. Due to the fact that many things can be represented as graphs, graph traversal has become a common task, especially used in data science and...
Graphs are one of the most useful data structures. They can be used to model practically everything - object relations and networks being the most common ones. An image can be represented as a grid-like graph of pixels, and sentences can be represented as graphs of words. Graphs are used...
