<div dir="ltr">OK, full disclosure, Tim has a point, the problems get pretty difficult by the time you get to 100 or so. For one of them (#152 I think), my algorithm took over 60 hours to run (doh! But it did give the correct answer - if it hadn't I'd have even less hair than I do!). Once you get the correct answer, you can always find a better/faster/cleaner solution in the forums (fora?). It is quite humbling.<div>

By the time you get to problem #60 you will have built a little toolbox of<br>
reusable functions (admittedly mostly in the number-theory area) and been<br>
exposed to many different ways to solve problems and many different<br>
programming languages.<br>

And by the time you get to problem #100, your head will hurt (but in a fun<br>
kind of way) :-)<br>
<br>
It's well worth checking out the math/number-theory module; there is a<br>
*lot* of cool stuff in there. Only big omission I have found for PE is<br>
that there is no way to prepare a cache of primes.<br>
