What is Span<T> and Memory<T>? Span<T> and Memory<T> are value types introduced in .NET Core 2.1 that provide type-safe and memory-safe representation of a contiguous region of arbitrary memory. They enable zero-copy slicing of arrays, strings, and other memory buffers without allocating new objects on the heap. Span<T> is a stack-only type (ref struct) that …

Override Identifier in C++ – Explained with Examples Imagine you have a parent and a child. The parent has a rule, like “Always be polite.” The child wants to follow the same rule but in their own way. In C++, when a child class follows (or overrides) a rule from the parent class, we use …
If you’re new to programming, learning C++ can seem intimidating. But don’t worry you’re not alone! You might notice that C++ has two types of data structures (structs) and classes (classes).At first glance, they might seem similar. After all, both can contain variables and functions. It’s important to understand how they behave under the hood …
In many real-world Java applications, you’ll receive strings that contain punctuation, symbols, or other non-alphanumeric “special” characters. Here, it’s important to clean up user input for search and normalize data. In this blog, we will learn how to clean this kind of data and replace it with spaces. You will learn here simply and easily. …

A Minimum Spanning Tree (MST) is a subset of edges in a connected, weighted graph that connects all vertices without forming a cycle and with the minimum possible total edge weight. In this blog post, we implement Prim’s Algorithm using a min-heap (priority queue) to efficiently calculate the MST. Minimum Spanning Tree in C++ Using …

The Bellman-Ford algorithm is a classical approach for finding the shortest path from a single source node to all other vertices in a weighted graph, even when the graph contains negative weight edges. Unlike Dijkstra’s algorithm, Bellman-Ford is capable of detecting negative weight cycles.In this post, we implement Bellman-Ford using a simple nested loop structure, …

Dijkstra’s Algorithm is one of the most important and widely used algorithms for finding the shortest path in a weighted graph with non-negative edges. In this blog post, we’ll implement Dijkstra’s algorithm using a priority queue (min-heap) in C++. The input will be in the form of an edge list, and the algorithm will return …

In this Blog, we will learn how to create a stopwatch using Java with clear code. A stopwatch is used to measure the time. We will create a simple and easy stopwatch here. After this, you can build your console-based stopwatch in Java What is Stopwatch A Stopwatch is used to measure the amount of time …

In this Blog, we will learn how the camel case works in Java with a clear and understandable example. In Java, camel case is nothing but a Naming Convention . I know you are thinking about what is naming convention is, it is a set of rules used to name variables, methods, etc. Some rules …
Cycle detection in an undirected graph requires a slightly different approach. Since every edge connects both ways, we must carefully track visited nodes and their parents to avoid false positives. Detecting Cycles in an Undirected Graph using BFS Idea Perform a BFS from every unvisited node (to handle disconnected graphs). If a visited node is …
