( [id://3333]=superdoc: print w/replies, xml ) Need Help??

Deal with the problem a little at a time. First bit is loop over the elements (with strictures, declarations and initialisation thrown in):

use warnings; use strict; my @times = (5, 10, 20, 25, 30, 40, 45, 50, 55, 65, 75, 80, 90); my @times1; my @times2; for my $elmt (@times) {

Then deal with the first case (and the special case for the first element):

if (! @times1 || $elmt - $times1[-1] >= 10) { push @times1, $elmt; next; }

Then deal with the second case (and again the special case for the first special element):

if (! @times2 || $elmt - $times2[-1] >= 10) { push @times2, $elmt; next; }

Then deal with the exception (and close the loop body):

push @times1, $elmt; }

Finally print the result:

print "Times1: @times1\n"; print "Times2: @times2\n";

Prints:

Times1: 5 20 30 40 50 65 75 90 Times2: 10 25 45 55 80

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.
