you need to make the old largest number the second_largest if there is a new largest one.
I fixed some other minor things as well.
#!/usr/bin/perl -w use strict; my @input = <DATA>; chomp @input; my $largest_value = 0; my $second_value = 0; for (@input){ #$value = substr($input[$i], 0, 6); why? Perl can dwal with floati +ng point numbers if($_ > $largest_value){ $second_value = $largest_value; $largest_value= $_; } elsif(($_ > $second_value) && ($_ < $largest_value)){ $second_value = $_; } } print "$largest_value $second_value\n"; __DATA__ 0.2430 0.0830 0.1320 0.0920 0.0180 0.0880 0.3440
0.3440 0.2430

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.
