in reply to TIMTOWTDI and other languages

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;
