    Ahh, good point ;-)

    Serves me right for trying to be creative on a Windows box sans Perl :)

      This is the variant I found most straightforward to use:
      use List::Util qw[min max]; $m = max(1,2);
      Here you go:

      This is how one can find a maximum number in an array iteratively and recursively in Perl

      #!/usr/bin/perl my (@setOfnumbers); @setOfnumbers = ( 9, 7, 90, 3, 8, 412, 67, 2, 45, 53, 1, 3,89 ); print "Finding maximum number iteratively ", getMaximumNumber(@setOfnumbers) , "\n"; print "Finding maximum number recursively ", findMaximumNumber(@setOfnumbers) , "\n"; #Finding maximum number iteratively sub getMaximumNumber{ my ($maximumNumber); $maximumNumber = @_[0]; foreach(@_){ if ($_ > $maximumNumber){ $maximumNumber = $_; } } return $maximumNumber; } #Finding maximum number recursively sub findMaximumNumber{ my ($maximumNumber); if (@_ == 1){ $maximumNumber = shift(@_); return $maximumNumber; } else{ $maximumNumber = shift(@_); return (findMaximumNumber(@_) > $maximumNumber) ? findMaximumNumber(@_) : $maximumNumber; } }
