A package to offer R solutions to Project Euler problems

euler

Overview

The goal of euler is to offer R solutions to Project Euler problems.

Installation

You can install the package directly from GitHub using the devtools package.

# install.packages("devtools")
install_github("nathaneastwood/euler")

Useage

We can, for example, solve Euler problem 3 using the following:

euler_3(600851475143)
[1] 6857

Or we could solve Euler problem 4 using the following:

euler_4(3)
[1] 906609

Explaining Methodology

You will notice that our code has minimal comments and that we haven’t provided any detail to how we came up with our solutions. We believe that in doing so, we would be taking away the fun for others. We came to this decision because of the nature of Project Euler. Take this excerpt from there website.

I learned so much solving problem XXX so is it okay to publish my solution elsewhere?

It appears that you have answered your own question. There is nothing quite like that “Aha!” moment when you finally beat a problem which you have been working on for some time. It is often through the best of intentions in wishing to share our insights so that others can enjoy that moment too. Sadly, however, that will not be the case for your readers. Real learning is an active process and seeing how it is done is a long way from experiencing that epiphany of discovery. Please do not deny others what you have so richly valued yourself.

We do, however, plan on writing about more general content aimed at solving maths problems (e.g. efficient code solutions for finding primes) in R, if not linked to specific problems.
