jsme vybrali několik jazyků.</p><p>Pokud Vás zajímají různé implementace, tak bychom doporučili „prohrabávat“ se přes ně v následujícím pořadí: <code>C# → Java → C++</code>. Důvod pro zvolené pořadí vychází z toho, že C# implementace je poměrně čitelná a obsahuje množství vysvětlujících komentářů. Implementace v Javě je stejně čitelná, ačkoli již s minimem komentářů, které se maximálně odkazují na CLRS. C++ implementace je „značně poznačená“ podtržítky ;)</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="c">C++<a href="#c" class="hash-link" aria-label="Direct link to C++" title="Direct link to C++">​</a></h3><p>V C++ si můžeme vybrat mezi 2 různými implementacemi (<code>clang</code> nebo <code>gcc</code>).</p><h4 class="anchor anchorWithStickyNavbar_LWe7" id="clang">clang<a href="#clang" class="hash-link" aria-label="Direct link to clang" title="Direct link to clang">​</a></h4><p>Hlavičkové soubory, které používáme při práci s množinou nebo slovníkem (zajímavé sekce jsou vytaženy):</p><ul><li><p><a href="https://github.com/llvm/llvm-project/blob/main/libcxx/include/map" target="_blank" rel="noopener noreferrer"><code>map</code></a></p><div class="language-cpp codeBlockContainer_Ckt0 theme-code-block" style="--prism-color:#000000;--prism-background-color:#ffffff"><div class="codeBlockContent_biex"><pre tabindex="0" class="prism-code language-cpp codeBlock_bY9V thin-scrollbar"><code class="codeBlockLines_e6Vv"><span class="token-line" style="color:#000000"><span class="token keyword" style="color:rgb(0, 0, 255)">template</span><span class="token plain"> </span><span class="token operator" style="color:rgb(0, 0, 0)">&lt;</span><span class="token keyword" style="color:rgb(0, 0, 255)">class</span><span class="token plain"> </span><span class="token class-name" style="color:rgb(38, 127, 153)">_Key</span><span class="token punctuation" style="color:rgb(4, 81, 165)">,</span><span class="token plain"> </span><span class="token keyword" style="color:rgb(0, 0, 255)">class</span><span class="token plain"> </span><span class="token class-name" style="color:rgb(38, 127, 153)">_Tp</span><span class="token punctuation" style="color:rgb(4, 81, 165)">,</span><span class="token plain"> </span><span class="token keyword" style="color:rgb(0, 0, 255)">class</span><span class="token plain"> </span><span class="token class-name" style="color:rgb(38, 127, 153)">_Compare</span><span class="token plain"> </span><span class="token operator" style="color:rgb(0, 0, 0)">=</span><span class="token plain"> less</span><span class="token operator" style="color:rgb(0, 0, 0)">&lt;</span><span class="token plain">_Key</span><span class="token operator" style="color:rgb(0, 0, 0)">&gt;</span><span class="token punctuation" style="color:rgb(4, 81, 165)">,</span><span class="token plain"></span><br></span><span class="token-line" style="color:#000000"><span class="token plain"> </span><span class="token keyword" style="color:rgb(0, 0, 255)">class</span><span class="token plain"> </span><span class="token class-name" style="color:rgb(38, 127, 153)">_Allocator</span><span class="token plain"> </span><span class="token operator" style="color:rgb(0, 0, 0)">=</span><span class="token plain"> allocator</span><span class="token operator" style="color:rgb(0, 0, 0)">&lt;</span><span class="token plain">pair</span><span class="token operator" style="color:rgb(0, 0, 0)">&lt;</span><span class="token keyword" style="color:rgb(0, 0, 255)">const</span><span class="token plain"> _Key</span><span class="token punctuation" style="color:rgb(4, 81, 165)">,</span><span class="token plain"> _Tp</span><span class="token operator" style="color:rgb(0, 0, 0)">&gt;</span><span class="token plain"> </span><span class="token operator" style="color:rgb(0, 0, 0)">&gt;</span><span class="token plain"> </span><span class="token operator" style="color:rgb(0, 0, 0)">&gt;</span><span class="token plain"></span><br></span><span class="token-line" style="color:#000000"><span class="token plain"></sp
