I received this question in email from one of my readers, and I thought it would be of general interest: I find myself with two arrays of the same size and I want to create a third that combines each element. What I want is something similar to var S3...
Here are my notes on the third Project Euler problem. The problem is "What is the largest prime factor of the number 600,851,475,143?" Once again, this is a problem that is best solved creating some simple LINQ queries. From the outside, this...
The second Euler problem asks you to find the sum of all even valued terms in the Fibonacci sequence which do not exceed 4,000,000. Let's look at the solution from the outside in. Here's the query that finds the answer: var EvenFibNumbers = (from...
I am starting a new series. A friend recently pointed me at the Project Euler problems. You can see the project here: http://projecteuler.net/ As I finish them, I'll post an explanation of the problem and the code here. I've also posted the code...
Dave Donaldson asks " Do you write software at homer like you do at work? " Dave wonders if we use the same discipline writing software at home (for our own use) that we do at work. I think the question is great, but I'm concerned about...
If you're like me, you understand new language features better when you see what the new language features generate for you. Closures in C# are no different. There's quite a bit that goes on under the covers in a C# closure. Looking at all the...
I keep finding more uses for extension methods. This time it's extending IComparable<T>. The API signature for IComparable<T> has been around since the dawn of C: if the left is less than the right, return something less than 0, if left...
