in reply to remove spaces after join operation

Hi lakssredhar,
A suggestions:
I need to print the column1 as a row outside the while loop so i used

... push @first_sentence,$arr[0]; }print join ' ',@first_sentence;
I was kind of thinking, why, push all the column 1 into an array variable, in work on the array outside the while loop.
what of if all work were done in the while loop? Like so:
use warnings; use strict; my $line; while (<DATA>) { my $part = (split)[0]; if (/[.()]/) { $line =~ s/\s*$//; $line .= $part; } else { $line .= $part . q[ ]; } } print $line; __DATA__ i o am o 2 o ( o but o ) o . o how o

If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
