 Need Help??
Al,
As promised, here is my inefficient code as written specifically for the Euler problem.
```#!/usr/bin/perl
use strict;
use warnings;
use Math::BigFloat;

my (\$max, \$suspect) = (0,0);

N:
for (2..999) {
my \$n = Math::BigFloat->new(1);
\$n->bdiv(\$_, 4000);
my (\$str) = \$n->bstr() =~ /(\d+)\1/;
my (\$best, \$orig) = ('', \$str);
while (1) {
my (\$long_match) = \$str =~ /(\d+)\1/;

last if ! defined \$long_match;
next N if \$long_match =~ /^(\d)\1+\$/;

# ensure we don't reduce too far
my \$len  = length(\$long_match);
my \$mult = int(length(\$orig) / \$len);
last if substr(\$orig, 0, \$len * \$mult) !~ /^(\$long_match)+\$/;

\$str = \$best = \$long_match;
}
my \$len = length(\$best);
(\$max, \$suspect) = (\$len, \$_) if \$len > \$max;
}
print "\$max\t\$suspect\n";

Cheers - L~R

 [Corion]: ambrus: Yes, ideally you would have the ease of overhead projection transparencies and pens drawing on them, combined with the computer generated slide text... [Corion]: Maybe the solution would be a tablet (with pens), like the Wacom tablets, but you still need good software and need to know how to operate it well in an interactive setting ;) [ambrus]: Corion: the solution depends on who for. Some non-math presentations need to show lots of graphics or photos, with fine details and color. For those, blackboard or overhead transparencies aren't so good (yes, you can print on transparencies, but there's s [ambrus]: ome quality limits), but film projection or computer projector is fine.
