In English, not Perl, you'd do it by:
  • For each line in the input,
    • Split the line into its pieces, separating the row ID from the data,
    • Assume the first is the biggest,
    • Walk down the indices, keeping track of which represents the largest, and
    • Report that answer
But Perl can look a lot like English if you stare at it for long enough:
foreach my $l (@line) { my ($row_id, @row_data) = split( /;/, $l ) ; my $idx = 0 ; do { $idx = $_ if $row[$_] > $row[$idx] } for 1..$#row_data ; print (1+$idx), "\n" ; }
but there's lots of ways to do it.

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.
