    The syntax of the function ’solver’ as explained in the rules is:
    colors = solver(A,[targetRow targetColumn])

    while in the distributed functions it is:
    colors = solver(A,targetRowAndColumn)
    This also fits the ‘testsuite_sample.mat’ is built.

    What is the correct one (should we use a linear index of the target or subscripts)?

    Thank you

    Everyone,

    Sorry about that. I wrote the contest code in absolute indexing, and then changed it to match the rules. I pushed the absolute indexing version accidentally. My bad.

    We just modified the rules to match the contest suite as it is on the File Exchange. Looks like some of the early entries figured it out and are doing well. Use ind2sub to convert to row column if you happen to need it.

    sorry,
    Doug

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
