G'day supriyoch_2008,

Here's a technique that involves using the lengths of the original strings as hash keys.

$ perl -Mstrict -Mwarnings -E ' use autodie qw{:all}; my $ext = ".txt"; my @nums = 1 .. 3; my %result; for (@nums) { open my $fh, "<", $_ . $ext; while (<$fh>) { chomp; y/,//d; next unless length; $result{+length} .= $_; } close $fh; } my @sorted_keys = sort { $a <=> $b } keys %result; say "*** Input Data Strings ***"; say "Shortest: ", $sorted_keys[0]; say "Longest: ", $sorted_keys[-1]; say "*** Output Data Strings ***"; say $result{$_} for @sorted_keys; say "*** Two Shortest ***"; say $result{$_} for @sorted_keys[0, 1]; say "*** Two Longest ***"; say $result{$_} for @sorted_keys[-2, -1]; ' *** Input Data Strings *** Shortest: 1 Longest: 5 *** Output Data Strings *** ATG AATTGG AAATTTGGG AAAATTTTGGGG AAAAATTTTTGGGGG *** Two Shortest *** ATG AATTGG *** Two Longest *** AAAATTTTGGGG AAAAATTTTTGGGGG

I'm not sure how much of your other output was actually required or just for debugging; regardless, you should be able to add code for that quite easily.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
