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;

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).
