Renamed `ioccc.ico` to `favicon.ico`. Correctly added use of `favicon.ico` to all constructed HTML headers. Fixed the smart quote in HTML elements problem. Moved HTML "DO NOT EDIT" comments down below at the bottom of the HTML phase 1 section. According to to the Nu Html Checker, a charset attribute on a meta element found after the first 1024 bytes. Changed `bin/md2html.sh` VERSION from "1.1.3 2024-03-28" to "1.2 2024-03-30". Improved `bin/gen-status.sh` to adjust the "status_update" value only when the "contest_status" is changed. Performed a `make www` to perform and test the above under macOS.

<p>This alternate code is for the <a href="https://en.wikipedia.org/wiki/0">very few</a>
|

<a href="https://en.wikipedia.org/wiki/Microsoft_Windows">users</a>
|
||
<a href="https://www.ioccc.org">here</a> who will need it. Nonetheless if you’re using
|
||
Turbo-C or MSC, the code is available, based on the authors’ remarks except that
|
||
the <code>" #Q"</code> string was not changed as that showed worse looking output instead
|
||
of improved output though admittedly we have no way to test the compilers in
|
||
question. YMMV.</p>

|
||
<h3 id="alternate-use">Alternate use:</h3>
|
||
<p>Use <code>baruch.alt</code> as you would <code>baruch</code>.</p>
|
||
<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p>This program reads an integer between 4 and 99 from the <code>stdin</code>.</p>
|
||
<p>NOTE: The original program did not have a newline at the end of the file. We
|
||
added a final newline to the file to make unpacking easy.</p>
|
||
<h2 id="authors-remarks">Authors’ remarks:</h2>
|
||
<p>The goal of this work was to write a program that solves the classic <a href="https://en.wikipedia.org/wiki/Eight_queens_puzzle">n-queens
|
||
problem</a>, with a board size
|
||
of up to 99x99, while keeping the program as short as possible.</p>
|
||
<p>The program finds all possibilities to place N chess queens on an NxN
|
||
<a href="https://en.wikipedia.org/wiki/Chessboard">chessboard</a> so that no queen is in
|
||
range of any other queen (not in the same column row or diagonal). For each
|
||
solution the chess board and the place of the queens is printed to stdout.</p>
|
||
<p>This program is about as simple and as readable as possible. To make things
|
||
even more simple we used a very limited subset of C:</p>
|
||
<ul>
|
||
<li>No pre-processor statements</li>
|
||
<li>Only one, harmless, <code>for</code> statement</li>
|
||
<li>No <code>if</code>s</li>
|
||
<li>No <code>break</code>s</li>
|
||
<li>No <code>case</code>s</li>
|
||
<li>No functions outside the standard C library</li>
|
||
<li>No <code>goto</code>s</li>
|
||
<li>No structures</li>
|
||
</ul>
|
||
<p>In short, it contains no C language that might confuse the innocent reader. :-)</p>
|
||
<p>This program demonstrates the claim that in C, any program can be written using
|
||
a single ‘for’ statement, as long as it is long enough.</p>
|
||
<h3 id="for-pc-users">For PC users:</h3>
|
||
<p>In order to compile the program under Turbo-C or MSC, <code>int</code> should be inserted
|
||
at the beginning of the program. For better looking results it is recommended
|
||
to replace the <code>" #Q"</code> string with <code>" \261\2"</code>.</p>
