The first entry in the logbook, and what this blog is for.

<p>Every contest starts the same way. You open problem A, write <code>main</code>, and print something to make sure the judge is listening.</p> <figure class="code"><figcaption><span class="mono">C++</span><button class="code-copy mono" type="button">Copy</button></figcaption><pre><code><span class="cp">#include</span><span class="w"> </span><span class="cpf">&lt;bits/stdc++.h&gt;</span> <span class="kt">int</span><span class="w"> </span><span class="nf">main</span><span class="p">()</span><span class="w"> </span><span class="p">{</span> <span class="w"> </span><span class="n">std</span><span class="o">::</span><span class="n">cout</span><span class="w"> </span><span class="o">&lt;&lt;</span><span class="w"> </span><span class="s">&quot;Hello, world</span><span class="se">\n</span><span class="s">&quot;</span><span class="p">;</span> <span class="p">}</span> </code></pre></figure> <p>This entry is that line for Field Notes.</p> <p>What comes next: stories from the work, from Pendle to problem setting to contests; algorithms worth explaining properly; and the occasional flex. Some entries will be in English, some in Vietnamese.</p> <p>The judge is listening. More soon.</p>
