<p>A lot of you probably know <a href="https://projecteuler.net/">Project Euler</a>.<br />
For those who don't here a short explanation: Project Euler is a collection of mathematical/programming problems.
Most problems consist of finding a single number and are solved by writing a program in the programming language of your choice.</p>
<p>Most people solve these by using normal languages like C, Java, Phyton, Haskell etc.
But you can also go a step further and try solving it with a little bit more exotic languages.</p>
<p>So here are my solutions written in <a href="http://esolangs.org/wiki/Befunge">Befunge</a></p>
<blockquote>
<p><strong>Note:</strong><br />
Similar to most Befunge content on this site I only used the Befunge-93 instruction-set but ignored the 80x25 size restriction.
<em>(Even so most programs here don't get this big.)</em></p>
