Various comments so far:
1.Antirice asked if I can repeat the numbers: Answer is yes:
ie.. [ [1,2],[4,2]] is allowed.
2. pzbagel: In mentioning of next if $n =~ /0\d+/;. \d+ was necessary to because I just don't wanted the formed-numbers that begins with 0. Anywhere else 0 in the number is fine. For 2x2 matrix this should work fine.
3. I like Rhose's appraoch as initiated by CountZero.
4. Other apporach:, Start forming matrix starting from the highest divisor.
4. Few other related challanges are
- Find a matrix for each divisor possible with lowest possible total of numbers in the matrix. ex.. [[1 2] [3,0]]:Total = 6
- Origianl matrix can have numbers with K digits. K > 1.
Example: K= 2 [ [12, 34],[56,78]]
- It could be NXNXN Matrix : Example: 3 x 3 x 3 Matrix: If we take K= 1 here, according to Rhose's approach we will have 1000/27 = 35 as maximum divisor.
Update: tall_man's answer at Re: Re: Matrix Formation is a good but rather cumborsum attempt. The best answer for 3x3 matrix -> Highest divisor is '44'. I am sure coming up with 4x4 or 15x15 matrix answers would be quite challanging.

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).
