<h1 id="61-">6.1 Хеш-таблица<a class="headerlink" href="#61-" title="Permanent link">¶</a></h1>
|
||
<p><u>Хеш-таблица (hash table)</u>, также называемая <u>таблицей рассеяния</u>, обеспечивает эффективный поиск элементов за счет отображения между ключом <code>key</code> и значением <code>value</code> . Иначе говоря, если передать в хеш-таблицу ключ <code>key</code> , то можно за <span class="arithmatex">\(O(1)\)</span> времени получить соответствующее значение <code>value</code> .</p>
|
||
<p>Как показано на рисунке 6-1, пусть есть <span class="arithmatex">\(n\)</span> студентов, и у каждого из них есть два поля данных: "имя" и "номер студенческого билета". Если мы хотим реализовать запрос вида "ввести номер студенческого билета и вернуть соответствующее имя", то для этого можно использовать показанную ниже хеш-таблицу.</p>
|
||
<p><a class="glightbox" href="../hash_map.assets/hash_table_lookup.png" data-type="image" data-width="100%" data-height="auto" data-desc-position="bottom"><img alt="Абстрактное представление хеш-таблицы" class="animation-figure" src="../hash_map.assets/hash_table_lookup.png" /></a></p>
|
||
<p align="center"> Рисунок 6-1 Абстрактное представление хеш-таблицы </p>
|
||
|
||
<p>Помимо хеш-таблицы, функции поиска можно реализовать и через массив, и через связный список. Сравнение их эффективности приведено в таблице 6-1.</p>
|
||
<ul>
|
||
<li><strong>Добавление элемента</strong>: нужно лишь добавить элемент в конец массива (или списка), что занимает <span class="arithmatex">\(O(1)\)</span> времени.</li>
|
||
<li><strong>Поиск элемента</strong>: так как массив (или список) неупорядочен, приходится обходить все элементы, что занимает <span class="arithmatex">\(O(n)\)</span> времени.</li>
|
||
<li><strong>Удаление элемента</strong>: сначала нужно найти элемент, затем удалить его из массива (или списка), что занимает <span class="arithmatex">\(O(n)\)</span> времени.</li>

<p>Нетрудно заметить, что <strong>операции чтения, добавления, удаления и обновления в хеш-таблице имеют временную сложность <span class="arithmatex">\(O(1)\)</span></strong> , то есть выполняются очень эффективно.</p>

<p>К базовым операциям хеш-таблицы относятся инициализация, поиск, добавление пар ключ-значение и удаление пар ключ-значение. Пример кода приведен ниже:</p>

<h2 id="612-">6.1.2 Простая реализация хеш-таблицы<a class="headerlink" href="#612-" title="Permanent link">¶</a></h2>
|
||
<p>Сначала рассмотрим самый простой случай: <strong>реализуем хеш-таблицу только с помощью одного массива</strong>. В хеш-таблице каждую пустую ячейку массива мы называем <u>бакетом (bucket)</u>, и каждый бакет может хранить одну пару ключ-значение. Следовательно, операция поиска сводится к тому, чтобы найти бакет, соответствующий <code>key</code> , и получить из него <code>value</code> .</p>
|
||
<p>Но как определить бакет, соответствующий заданному <code>key</code> ? Это делается с помощью <u>хеш-функции (hash function)</u>. Назначение хеш-функции - отображать большое входное пространство в меньшее выходное пространство. В хеш-таблице входным пространством являются все <code>key</code> , а выходным - все бакеты (индексы массива). Иначе говоря, передав <code>key</code> на вход, <strong>мы можем через хеш-функцию получить позицию хранения соответствующей пары ключ-значение в массиве</strong>.</p>
|
||
<p>Процесс вычисления хеш-функции для одного <code>key</code> включает два шага.</p>
|
||
<ol>
|
||
<li>Сначала с помощью некоторого хеш-алгоритма <code>hash()</code> вычисляется хеш-значение.</li>
|
||
<li>Затем хеш-значение берется по модулю числа бакетов (длины массива) <code>capacity</code> , чтобы получить бакет (индекс массива) <code>index</code> , соответствующий этому <code>key</code> .</li>
|
||
</ol>
|
||
<div class="highlight"><pre><span></span><code><a id="__codelineno-26-1" name="__codelineno-26-1" href="#__codelineno-26-1"></a><span class="nv">index</span><span class="w"> </span><span class="o">=</span><span class="w"> </span>hash<span class="o">(</span>key<span class="o">)</span><span class="w"> </span>%<span class="w"> </span>capacity
|
||
</code></pre></div>
|
||
<p>После этого можно использовать <code>index</code> для доступа к соответствующему бакету в хеш-таблице и получения <code>value</code> .</p>
|
||
<p>Пусть длина массива <code>capacity = 100</code> , а хеш-алгоритм <code>hash(key) = key</code> . Тогда легко получить хеш-функцию <code>key % 100</code> . На рисунке 6-2 на примере <code>key</code> "номер студенческого билета" и <code>value</code> "имя" показан принцип работы хеш-функции.</p>

|

<p>Ниже приведен код простой реализации хеш-таблицы. В нем мы инкапсулируем <code>key</code> и <code>value</code> в класс <code>Pair</code> , чтобы представить пару ключ-значение.</p>

<h2 id="613-">6.1.3 Хеш-коллизии и расширение<a class="headerlink" href="#613-" title="Permanent link">¶</a></h2>
|
||
<p>По сути, хеш-функция отображает входное пространство, состоящее из всех <code>key</code> , в выходное пространство, состоящее из всех индексов массива, а входное пространство обычно значительно больше выходного. Поэтому <strong>теоретически неизбежно существование ситуации "несколько входов соответствуют одному выходу"</strong>.</p>
|
||
<p>Для хеш-функции из приведенного выше примера, если последние две цифры <code>key</code> совпадают, то совпадает и результат хеш-функции. Например, если искать студентов с номерами 12836 и 20336, то получим:</p>
|
||
<div class="highlight"><pre><span></span><code><a id="__codelineno-40-1" name="__codelineno-40-1" href="#__codelineno-40-1"></a><span class="m">12836</span><span class="w"> </span>%<span class="w"> </span><span class="nv">100</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="m">36</span>
|
||
<a id="__codelineno-40-2" name="__codelineno-40-2" href="#__codelineno-40-2"></a><span class="m">20336</span><span class="w"> </span>%<span class="w"> </span><span class="nv">100</span><span class="w"> </span><span class="o">=</span><span class="w"> </span><span class="m">36</span>
|
||
</code></pre></div>
|
||
<p>Как показано на рисунке 6-3, два номера указывают на одно и то же имя, что, очевидно, неверно. Такую ситуацию, когда нескольким входам соответствует один и тот же выход, называют <u>хеш-коллизией (hash collision)</u>.</p>

|
||
<p align="center"> Рисунок 6-3 Пример хеш-коллизии </p>
|
||
|
||
<p>Легко понять, что чем больше емкость хеш-таблицы <span class="arithmatex">\(n\)</span> , тем ниже вероятность того, что несколько <code>key</code> попадут в один и тот же бакет, а значит, тем меньше коллизий. Поэтому <strong>мы можем уменьшать число хеш-коллизий путем расширения хеш-таблицы</strong>.</p>
|
||
<p>Как показано на рисунке 6-4, до расширения пары ключ-значение <code>(136, A)</code> и <code>(236, D)</code> конфликтовали, а после расширения коллизия исчезла.</p>
|
||
<p><a class="glightbox" href="../hash_map.assets/hash_table_reshash.png" data-type="image" data-width="100%" data-height="auto" data-desc-position="bottom"><img alt="Расширение хеш-таблицы" class="animation-figure" src="../hash_map.assets/hash_table_reshash.png" /></a></p>
|
||
<p align="center"> Рисунок 6-4 Расширение хеш-таблицы </p>
|
||
|
||
<p>Подобно расширению массива, расширение хеш-таблицы требует перенести все пары ключ-значение из старой таблицы в новую, а это очень затратно по времени; кроме того, поскольку емкость хеш-таблицы <code>capacity</code> изменилась, нам приходится с помощью хеш-функции заново вычислять позиции хранения всех пар ключ-значение, что дополнительно увеличивает вычислительные расходы процесса расширения. Поэтому языки программирования обычно заранее резервируют достаточно большую емкость хеш-таблицы, чтобы избежать частых расширений.</p>
|
||
<p><u>Коэффициент загрузки (load factor)</u> - важное понятие хеш-таблицы. Он определяется как отношение числа элементов в хеш-таблице к числу бакетов и используется для оценки степени серьезности хеш-коллизий, <strong>а также часто служит условием срабатывания расширения хеш-таблицы</strong>. Например, в Java, когда коэффициент загрузки превышает <span class="arithmatex">\(0.75\)</span> , система расширяет хеш-таблицу до <span class="arithmatex">\(2\)</span> раз от исходной емкости.</p>
