<h2>概要</h2>
<p>同じ型の2つの値、もしくは<code><a href="../initializer_list/initializer_list.html">initializer_list</a></code>によるN個の値のうち、最小値と最大値の組を取得する。</p>
<p>最後の引数<code>comp</code>は、2項の<a class="cpprefjp-defined-word" data-desc="boolを返す関数・関数オブジェクト。predicate">述語</a>関数オブジェクトであり、これを使用して比較演算をカスタマイズすることができる。</p>
<h2>要件</h2>
<ul>
<li>型<code>T</code>が<code>operator<</code>による比較が可能であること。</li>
<li><code><a href="../initializer_list/initializer_list.html">initializer_list</a></code>バージョンはそれに加えて、要素数が1以上であり、<code>T</code>がコピーコンストラクト可能であること。</li>
</ul>
<h2><a class="cpprefjp-defined-word" data-desc="関数呼び出し式の評価結果となるオブジェクト・値">戻り値</a></h2>
<p><code>first</code>が最小値、<code>second</code>が最大値となる<code><a href="../utility/pair.html">pair</a></code>オブジェクト</p>
<h2><a class="cpprefjp-defined-word" data-desc="関数等の意味論を構成する要素の1つ。Complexity。関数が使うアルゴリズムの空間計算量・時間計算量">計算量</a></h2>
<ul>
<li>2値比較バージョンは1操作。</li>
<li><code>initializer_list</code>バージョンは高々<code>(3/2) * t.size()</code>回の<a class="cpprefjp-defined-word" data-desc="boolを返す関数・関数オブジェクト。predicate">述語</a>適用。</li>
</ul>
<h2>備考</h2>
<ul>
<li>(1), (2) : 引数に一時オブジェクトを与えた場合、<code>minmax</code>の呼び出しを含む<a class="cpprefjp-defined-word" data-desc="完結式。full-expression。主に他の式の部分式ではない式。要するに一番外側の式。">完全式</a>の評価が終わる時点で、返された参照の寿命が切れる(<a class="cpprefjp-defined-word" data-desc="dangling。寿命が尽きた無効なオブジェクトやメモリ領域を、ポインタ・参照・イテレータなどが指し続けている状態のこと。これらにアクセスすると未定義の動作を引き起こす">ダングリング</a>)ことに注意：</li>
