There's several different ways I can think of:
  • Use Algorithm::Shuffle to randomly shuffle the list, then grab the first 5 items from it. If you are removing items from the list, and don't care about order, and doing this often, this might be the best way, but will be slow with a very large array.
  • Generate a random number from 0 to the size of your array. Splice out that item from the array. Repeat 4 more times.
  • Variation of either of the above if you want to keep your array intact is to use a new array , (0..scalar @array-1) as the array to modify; once you have your items from here, treat these as indices to your main array.

It's not what you know, but knowing how to find it if you don't know that's important

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.
