Описание
Реализована задача подсчёта количества слов в строке.
В последовательной (SEQ) версии алгоритм проходит по строке и считает количество переходов от пробельного символа к непробельному — каждый такой переход соответствует началу нового слова. Пустая строка возвращает 0 слов.
В параллельной (MPI) версии входной буфер сначала делится между процессами с помощью MPI_Scatterv; каждый процесс локально считает слова в своём фрагменте и выполняет корректировку при возможном разрыве слова на границе блоков (обмен последними/первым символами соседних блоков через MPI_Sendrecv). Локальные результаты суммируются через MPI_Reduce; итог затем распространяется на все процессы через MPI_Bcast и записывается в выходной буфер (это необходимо для корректной проверки на всех ранках).
