Separate versions (one optimized for speed, one for beauty :-) areok.  Post your code so we can time it on our own systems. 0)  Factorial Test  (numerics and function calls)         (we did this already) 1)  Regular Expressions Test     Read a file of (extended per egrep) regular expressions (one per line),     and apply those to all files whose names are listed on the command line.    Basically, an 'egrep -f' simulator.  Test it with 20 "vt100" patterns    against a five /etc/termcap files.  Tests using more elaborate patters    would also be interesting.  Your code should not break if given hundreds    of regular expressions or binary files to scan.   2)  Sorting Test     Sort an input file that consists of lines like this         var1=23 other=14 ditto=23 fred=2     such that each output line is sorted WRT to the number.  Order    of output lines does not change.  Resolve collisions using the    variable name.   e.g.         fred=2 other=14 ditto=23 var1=23      Lines may be up to several kilobytes in length and contain    zillions of variables. 3)  System Test     Given a list of directories, report any bogus symbolic links contained    anywhere in those subtrees.  A bogus symbolic link is one that cannot    be resolved because it points to a nonexistent or otherwise    unresolvable file.  Do *not* use an external find executable.    Directories may be very very deep.  Print a warning immediately if the    system you're running on doesn't support symbolic links.  I'll post perl solutions if people post the others.  --tom-- Tom Christiansen      Perl Consultant, Gamer, Hiker      tchrist@mox.perl.com  "But Billy!
