@data = (0,3,1,2,4); max(@data); min(@data); sub max() { my @numlist; my $cur,$max=0; @numlist = @_; $cur = 0; $max = 0; foreach $num (@numlist) { $cur = $num; if ( $cur > $max ) { $max = $cur; } print "$num\n"; } print "max = $max\n"; } sub min() { my @numlist; my $cur,$min=0; @numlist = @_; $cur = 0; $max = 0; foreach $num (@numlist) { $cur = $num; if ( $cur < $min ) { $min = $cur; } print "$num\n"; } print "min = $min\n"; }
