Given a positive integer n, generate a square matrix filled with elements from 1 to n2 in spiral order in C++

To generate a square matrix filled with elements from 1 to n^2 in spiral order in C++:
- Declare a 2D vector to store the result matrix.
- Implement a spiral order traversal algorithm using four loops to fill the matrix.
- Print the generated matrix as the result.

Reverse Linked List iterative and recursive in C++

To reverse a linked list in C++, there are two approaches: iterative and recursive.
In the iterative approach, three pointers are used: prev, curr, and temp.
The list is iterated until curr becomes NULL, and each node's next pointer is reversed.
The C++ code provided demonstrates both the iterative and recursive solutions.

Event-Driven Architectures: Building Scalable and Resilient Systems ✨

An event-driven architecture revolves around events, which are state changes or actions within a system.
Events enable asynchronous communication, decoupling services and improving scalability.
Producers publish events, which are captured and consumed by different parts of the system.
Choosing the right event management tool is crucial, with popular libraries including Kafka, RabbitMQ, and Redis Streams.

Run LLMs Locally with Ollama & Semantic Kernel in .NET: A Quick Start

In this post, you’ll learn how to set up Ollama on your machine, pull and serve a local model like llama3.2. and integrate it with Semantic Kernel in a .NET 9 project.
Ollama is a self-hosted platform for running language models locally. It eliminates the need for external cloud services and offers data privacy, lower costs, and ease of setup benefits.
Semantic Kernel is an open-source SDK from Microsoft that enables developers to seamlessly integrate AI capabilities into .NET applications.
The article lists the prerequisites to run Ollama and Semantic Kernel locally in a .NET 9 project.
The article shares a step-by-step integration guide for running locally hosted AI models.
The article also offers sample code and output to help understand how local, generative Artificial intelligence works with Ollama and Semantic Kernel.
Running AI models locally offers a few use cases including prototyping without incurring cloud costs, internal knowledge bases, and edge or offline applications.
Combining Ollama and Semantic Kernel lays a foundation for building self-contained, high-performance .NET applications that help maintain complete control over environment and reducing both complexity and recurring costs.
Further experimentation with Ollama and Semantic Kernel is encouraged, along with experimentation with different models in Ollama.
Upcoming posts will tackle Retrieval Augmented Generation(RAG) to give LLMs context-aware responses sourced from your own data-all running entirely on local infrastructure.

Given an array of non-negative integers determine if you are able to reach the last index in C++

Given an array of non-negative integers, you are initially positioned at the first index of the array.
Each element in the array represents your maximum jump length at that position.
Determine if you are able to reach the last index.
The solution involves checking if it is possible to reach the last index using the given jump lengths.

Rain water trapping

Given n non-negative integers representing an elevation map where the width of each bar is 1, compute how much water it is able to trap after raining.
This problem can be solved in many different ways. Namely: Brute force, Dynamic Programming and Two Pointers.
The brute force solution involves calculating the amount of water stored in each individual bar and then summing up all the individual elements to get the output.
The two pointers solution uses two pointers to iterate over the input and calculate the result.
The dynamic programming solution stores left and right maximum height values in an array to avoid iterating over all the elements every time.
The time complexity of the brute force solution is O(n^2).
The time complexity of the two pointers solution is O(n) as it iterates over the input set only once.
The time complexity of the dynamic programming solution is O(n) as it also iterates over the input set only once.
The space complexity of the brute force solution is O(1), of the two pointers solution is O(1) and of the dynamic programming solution is O(n).
The output format for this problem is in the form of a json object with the summary lines in an array called 'summary'.

Group Anagrams in C++

The given problem involves grouping anagrams together in a given array of strings.
The solution uses a map to store the sorted version of each string as the key and a vector to store the corresponding values.
The input strings are sorted and added to the map with the sorted version as the key.
Finally, the values in the map are copied to a 2D vector, representing the grouped anagrams.

Understanding Data Types in Programming

Primitive data types are the most basic forms of data types and are usually built into the programming language.
Common primitive data types include: Integer (int), Float (or Double), Character (char), Boolean (bool), and String.
Integer is used to represent whole numbers, Float represents real numbers or numbers with fractional parts.
Character is used to store single characters, Boolean represents a binary value, and String represents a sequence of characters used to represent text.

Understanding Variables and Data Types in JavaScript

JavaScript is a dynamic, loosely-typed language that allows variables to change type at runtime.
Variables in JavaScript are containers for storing data values and can be declared using var, let, or const.
JavaScript has different data types including primitive types (string, number, boolean, null, undefined, symbol, and bigint) and reference types (object, array, and function).
Type coercion and type checking are important concepts in JavaScript to handle data type conversions and check variable types.

React Native’s New Architecture: Sync and async rendering

React Native's New Architecture improves performance, developer experience, and aligns with React's features.
React Native's New Architecture includes synchronous layout updates, concurrent rendering, JavaScript Interface (JSI), and support for advanced React 18+ features.
The New Architecture removes the asynchronous bridge between JavaScript and native, replacing it with JSI for shared memory between the two layers, significantly improving performance.
The New Architecture includes backward compatibility with libraries targeting the old architecture.
Implementing synchronous updates via the useLayoutEffect Hook in React can avoid visual glitches and improve user experience.
The React Native team has created an app to compare the old and New Architectures and identify performance gaps.
If you use React Native 0.76 or later, the New Architecture is the default, requiring no additional configuration.
