Project Euler – Problem 2

So, here’s my take on the next Project Euler problem.

Problem 2 is indicated as follows:

Each new term in the Fibonacci sequence is generated by adding the previous two terms. By starting with 1 and 2, the first 10 terms will be:
1, 2, 3, 5, 8, 13, 21, 34, 55, 89, …
By considering the terms in the Fibonacci sequence whose values do not exceed four million, find the sum of the even-valued terms.

The first we can try is an obvious solution – try to go over every number in the Fibonacci sequence, check if it’s even valued, and add it to the accumulator if it is. Continue reading “Project Euler – Problem 2”

Project Euler

Some time ago I stumbled upon a very interesting project – http://projecteuler.net. As is stated on the projects page “Project Euler is a series of challenging mathematical/computer programming problems.” These problems are a great way to exercise the mind. Please note that the problems do require some mathematical/programming knowledge. However, you are not limited to just one way of finding the solution – there are multiple ways to come to an answer.

In the following post I will try to explain how I came to a certain answer (but I will not post the answers). The point of these post is to get you on the right track. It’s more rewarding to find the answers by yourself. However, if you are truly desperate, I will be posting working solutions that you can use to calculate the answer – but where is the challenge in that?

Also, please note that I’m using these problems to get a bit more familiar with the possibilities of PowerShell. As such, most of the solutions will be in PowerShell scripting language.

SharePoint Management Shell commands in PowerShell

SharePoint Management Shell is your best friend – you can do virtually anything on your SharePoint 2010 farm through it. However, it always bothers me that I cant use the right click paste I’m used to in PowerShell.

If we take a look at the SharePoint Management Shells Start menu link, we notice that it’s just a simple PowerShell window with some additional commands on top. As such, we can turn any PowerShell window into a SharePoint Management Shell. Just run

Add-PsSnapin Microsoft.SharePoint.PowerShell

in a PowerShell window and all the SharePoint management commands are yours to use.

Hello, World!

Hi,

my name is Tadas and this is my blog 🙂

Mostly I will be writing about technology, programming, and similar stuff – the things that fascinate me. Or just note down some piece of useful or interesting information. I hope you will enjoy reading my posts.
