When dealing with hierarchical data, like organizational charts or directory structures, Recursive Common Table Expressions (CTEs) in SQL Server offer a powerful way to traverse these relationships efficiently. Let’s walk through a structured approach to mastering Recursive CTEs in T-SQL. We’ll cover use cases, break down performance tips, and test our solution to highlight the…
In software development, especially with C#, we often encounter two design principles: inheritance and composition. Both help us build flexible, maintainable code, but knowing when to use one over the other is key to creating robust applications. Enter the principle of Composition over Inheritance, an approach that advocates for structuring code to maximize modularity, testability,…
If you’ve ever needed to tweak your .csproj file in Visual Studio but found yourself scratching your head trying to figure out how to do it, you’re not alone. I recently discovered a simple way to edit the .csproj file directly from the Solution Explorer, and I’m sharing it here to save you some time…
Let’s get one thing straight: programming isn’t just about writing code that works; it’s about writing code that doesn’t make you or your colleagues want to rip their hair out the next time they read it. One such gem in C# that helps keep code readable and maintainable is method overloading. So, what is it,…
When initializing variables, it is always best practice to provide an initial value. For value types, this is typically straightforward, as shown below: However, handling reference types can be more nuanced. There may be situations where you wish to declare a reference variable without immediately instantiating an object. In these cases, initializing a reference type…
When it comes to solving the Fibonacci sequence in code, there’s more to the story than meets the eye. Sure, it’s just a sequence where each number is the sum of the two preceding ones, but like most things in programming, the devil is in the details—especially when deciding how to calculate it: recursion or…
When given two strings, the goal is simple: determine whether they are anagrams of each other. An anagram is defined as a string that, when its letters are rearranged, forms another string. Both strings must have the same characters in the same frequency, regardless of the order. Let’s walk through a clean, structured approach to…
Ah, the timeless debate of declaring variables: should we throw them all at the top of the method like we’re organizing a toolset, or be modern and scatter them throughout the code like breadcrumbs? I’ve spent enough time mulling this over, and naturally, I’m here to tell you that, as always, it depends. (I know,…
In this post, we’re going to tackle the Two Integer Sum problem. Given an array of integers and a target sum, the task is to return the indices of two numbers whose sum equals the target. The solution needs to return the indices in increasing order. This is a common algorithm problem that can be…
Alright, let’s talk about duplicates. You’ve got an array of numbers, and your job is to figure out if any of those numbers make more than one appearance. Seems simple, right? Well, as straightforward as it may sound, this is one of those classic coding problems that gets right to the heart of efficient problem-solving….
