@classmates = (@classmates, &M1(@n));
Just a quick check reveals: > perl -lwe'use Benchmark "cmpthese";@a=0..8;cmpthese(-8, {push => sub
+{push@x,@a[0..2]}, comb => sub{@y=(@y,@a[0..2])}})'
Benchmark: running comb, push , each for at least 8 CPU seconds ...
comb: 28 wallclock secs (28.33 usr + 0.00 sys = 28.33 CPU) @ 44.7
+9/s (n=1269)
push: 8 wallclock secs ( 8.13 usr + 0.25 sys = 8.38 CPU) @ 4172
+8.04/s (n=349681)
Rate comb push
comb 44.8/s -- -100%
push 41728/s 93056% --
I know your arrays aren't growing linearly like this, so the difference wouldn't be so extreme.

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).

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