Euler Problem 14: Learn to Memoize

This is going to be fun. It’s a bit of LINQ, a bit of academic Computer Science, and a bit of meteorology. Euler Problem 14 concerns a sequence referred to as hailstorm numbers. Hailstorm number...

Long time, no Euler (or YAEPS # 13)

Well, it’s been a long time since I’ve taken the time to solve and blog about one of the Euler problems.  It was time to pick this up again. Problem 13 says: Work out the first 10 digits of the sum...

Euler Problem 10

Patrick posted his solution earlier this week. I figure it was time to add mine. Also, Octavio Hernandez pointed out in the comments to problem 8 that he had discussed similar code constructs in his blog...

Euler Problem 7

Yes, it's true that I've been very lax in working on these problems. It's been a combination of the day job, finishing all the editing tasks on "More Effective C#", and actually trying...

Notes on Euler Problem 3

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...

Discussion on Project Euler Problem 2

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...

Project Euler: Problem 1

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...
