1. Сконструировать и реализовать свою хеш таблицу
|
||||
|
||||
- изначальный размер 8, коэф-т загрузки 0.75
|
||||
|
||||
- Преобразование подаваемого данного в индекс с помощью хеш функции(в ручну) пример: полиномиальный хеш
|
||||
|
||||
- Коллизии обрабатываются методом цепочек, каждая корзина таблицы - список в котором хранятся пары значений key-value
|
||||
|
||||
- При превышении коэф-та загрузки происходит перехеширование таблицы, размер увеличивается вдвое, все пары заново вставляются в таблицу.
|
||||
|
||||
2. Читаем текстовый файл, разбивает на слова, приводим к нижнему регистру, подсчитываем повторения каждого слова: key - слово, value - кол-во повторений
|
||||
|
||||
- На вывод 10 самых встречающихся слов, для каждого слова выводим: ind(hash), key, value
