Project Euler

Quick post because I started talking to a friend about this.

ProjectEuler is a website which you can either describe as math problems designed as programming problems, or programming problems designed as math problems.

Either way, it’s fun.

The first and most tutorial-ish question is:

Find the sum of all the multiples of 33 or 55 below 10001000.

And another problem with a short problem statement:

4075540755 is a triangle number that is also pentagonal and hexagonal. Find the next.

The best thing about this is each problem has a number for its answer. So you can suffer by waiting 24 hours for your inefficient program to run or try to find something that runs in less than a minute.

Once you get in, ask me for my friend key so that you can see my progress’s if you’re interested.
