Landon Curt Noll a1c86c8a7a add original C links to entry navigation bars
The navigation bar for a winning entry now has a "_Original C_" link
(between the ✅ and the Inventory on the right hand side) so that one
may easily view the original C code that was submitted for IOCCC judging.

Ran `make www timestamp` to perform the above.

<p>The current status of this entry is:</p>

<p><strong>STATUS: INABIAF - please DO NOT fix</strong></p>

<h2 id="alternate-code">Alternate code:</h2>
<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-build">Alternate build:</h3>
<pre><code> make alt</code></pre>
<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>It is advisable to commence with relatively small integers, as the
duration and quantity of output can become substantial as the input
integer increases.</p>
<p>For instance, on a relatively generic computer in 2025, the following
execution times and output quantities were recorded:</p>
<pre><code> | input | clock | user | system | lines of |
| value | time | time | time | output |
|-------|---------------------|---------------------|------------------|--------------|
| 4 | 0.001s | 0.001s | 0.001s | 11 |

<p><strong>NOTE</strong>: 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>
