in reply to Simple Logic Problem with Perl

Here's my stab at it:

use strict; use warnings; use Data::Dumper; my $sample1 = ['str1 str2 1', 'str3 str4 2', 'str5 str6 3', 'str7 str8 4', 'str9 str10 5']; my $sample2 = ['str1 str2 0', 'str3 str4 4']; my $sample3 = ['str1 str2 3', 'str3 str4 4']; get_column($sample1); sub get_column { my $ar = shift; my $all; foreach my $str ( @{$ar} ) { my @ar = (split " ",$str); push @{$all}, [ @ar ]; } my @clean; my $diff; foreach my $i ( 1..$#{$all} ) { $diff = abs($all->[$i][2]- $all->[$i-1][2] ); print "$i\t$diff\n"; if ( $diff == 1 ) { push @clean, $all->[$i-1][0]; } if ( $diff > 1 ) { push @clean, $all->[$i-1][0], $all->[$i-1][1], $all->[$i][ +0], $all->[$i][1]; } if( $diff == 1 && $i == $#{$all} ){ push @clean, $all->[$i][0], $all->[$i][1]; } } print Dumper \@clean; return ; }
