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>Note that some compilers will be unable to compile the expression <code>X=g()...</code> in
|

<code>main()</code> due to lack of temporary stack space. One might want to try replacing
|
||
<code>main()</code> with:</p>
|
||
<div class="sourceCode" id="cb3"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb3-1"><a href="#cb3-1" aria-hidden="true" tabindex="-1"></a>main<span class="op">(){</span>X<span class="op">=</span>s<span class="op">().</span>v<span class="op">().</span>o<span class="op">().</span>o<span class="op">().</span>l<span class="op">().</span>S<span class="op">().</span>d<span class="op">().</span>l<span class="op">().</span>i<span class="op">().</span>o<span class="op">().</span>w<span class="op">().</span>N<span class="op">();}</span></span></code></pre></div>
|
||
<p>if this is a problem, which is what this alternate code is.</p>
|

<p>NOTE: it prints something else and it is what the author suggested one try as
|
||
well.</p>

<h2 id="judges-remarks">Judges’ remarks:</h2>
|
||
<p>This program prints out a string. Can you figure out how
|
||
it is done?</p>
|
||
<p>By use of pointers to functions returning a struct of pointers
|
||
to functions!</p>
|
||
<h3 id="spoiler">Spoiler:</h3>
|
||
<p>This program prints out the string:</p>
|
||
<blockquote>
|
||
<p>the quick brown fox jumped over the lazy dog</p>
|
||
</blockquote>
|
||
<h2 id="authors-remarks">Author’s remarks:</h2>
|
||
<p>It is simple to make the program print other strings. Each
|
||
alphabetical character from a to z is printed out as its
|
||
opposite:</p>
|
||
<pre><code>a->z b->y c->x etc</code></pre>
|
||
<p>To encode a new string input the string as it is meant to come out:</p>
|
||
<div class="sourceCode" id="cb7"><pre class="sourceCode c"><code class="sourceCode c"><span id="cb7-1"><a href="#cb7-1" aria-hidden="true" tabindex="-1"></a>X<span class="op">=</span>s<span class="op">().</span>v<span class="op">().</span>o<span class="op">().</span>o<span class="op">().</span>l<span class="op">().</span>S<span class="op">().</span>d<span class="op">().</span>l<span class="op">().</span>i<span class="op">().</span>o<span class="op">().</span>w<span class="op">().</span>N<span class="op">();</span></span></code></pre></div>
|
||
<p>Note: <code>S()</code> represents a space and <code>N()</code> a newline. This will now
|
||
produce…</p>
|
||
<pre><code>hello world</code></pre>
|
||
<p>By the way, there is actually a piece of code which is not used
|
||
in the original program! I leave it as an intellectual exercise
|
||
to the reader to find out what it is.</p>
