URL: https://www.progressiverobot.com/trie-data-structure-in-c-plus-plus/ A Trie data structure acts as a container for a dynamic array. In this article, we shall look at how we can implement a Trie in C/C++. This is based on the tree data structure but does not necessarily store keys. Here, each node only has a value, which is defined based on […]
In this tutorial, you’ll learn about the most important data types native to Ruby: integers, floats, strings, symbols, arrays, and hashes. This is not an exhaustive investigation of data types, but it will help you become familiar with the options you have available to you in your programs.
Visibility in the Go programming language means the file space from which a package or other construct can be referenced. In this article, you will learn how to control package visibility, as well as how to protect parts of your code that should only be used inside your package. To do this, we will create a basic logger to log and debug messages, using packages with varying degrees of item visibility.
In this tutorial, you will use the Go flag -ldflags to change the value of variables at build time and introduce your own dynamic information into a binary, using a sample application that prints version information to the screen. This passes a flag to the underlying Go toolchain linker, cmd/link, that allows you to change the values of imported packages at build time from the command line.

Today we will look into Builder pattern in java. Builder design pattern is a creational design pattern like [Factory Pattern](/community/tutorials/factory-design-pattern-in-java "Factory Design Pattern in Java") and [Abstract Factory Pattern](/community/tutorials/abstract-factory-design-pattern-in-java "Abstract Factory Design Pattern in Java"). Builder Design Pattern  Builder pattern was introduced to solve some of […]
Composite pattern is one of the Structural design pattern. Composite design pattern is used when we have to represent a part-whole hierarchy. Composite Design Pattern  When we need to create a structure in a way that the objects in the structure has to be treated the same way, we can […]
En Go, una etiqueta de compilación, o una restricción de compilación, es un identificador añadido a un fragmento de código que determina el momento en que debería incluirse el archivo en un paquete durante el proceso build. Esto le permite compilar diferentes versiones de…
Difference between Abstract Class and Interface is one of the popular interview questions. Abstract Class and Interface are a core part of the Java programming language. Whether to choose an interface or abstract class is a design decision that every architect faces. In my last articles, I have provided as much as possible details about […]
In this article, we will learn to solve the fractional knapsack problem using C++. We will start by looking at the problem statement and then move to the solution. This problem is one of many popular classical problems. It is fairly different than its sibling 0-1 knapsack and [0-N knapsack](/community/tutorials/solving-0-n-knapsack-problem-in-cpp). This is a greedy algorithm […]
