Here's a ruby example
alphas = [9, 4, 3, 2, 22, 13, 7, 140, 95, 278] betas = [8, 3, 4, 1, 278, 94, 15, 7, 19, 200] result = (alphas & betas).sort
There's a quite a few other ways to do it too, but I liked that one the most.

Update: Noticing a somewhat lack of variety in the languages used here's a python example too

alphas = [9, 4, 3, 2, 22, 13, 7, 140, 95, 278] betas = [8, 3, 4, 1, 278, 94, 15, 7, 19, 200] result = [] for x in alphas: if x in betas: result.append(x) result.sort()
This is probably the more obvious path, but if you like your tools functional ...
result = filter(lambda y: y != 0, [x in betas and x for x in alphas]) result.sort()
The closest I can get in perl is this (map == list comprehension?)
@result = sort { $a <=> $b } map { my $x = $_; grep $x == $_, @betas } @alphas;



update: added python examples
update2: added perl version of last python example

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 or How to display code and escape characters are good places to start.
