[Mutha_X]

Автор, предлагаю тему в формат статьи переделать (+ в репу будет ) и добавить вот что:
* сравнение производительности твоего кода для длинной строки (с jit и без) (можно взять ipsum lorem бла бла бла...) и для короткой (уже ты сделал);
* Всё тоже самое, но немного для другой реализации (смотри ниже код);
* Указать на каком процессоре и на какой системе получены результаты (я наблюдал ощутимую разницу в производительности аналогичных между собой решений на павне в зависимости от архитектуры проца);

pawn Code:
