 <!-- 9. Генератор случайных чисел.
 Функция rand представляет собой linear congruential generator (то есть, целочисленное умножение на константу и сложение с константой), возвращающий 32-битные целые случайные числа.
 Она реализована так, чтобы несколько потоков случайных чисел вычислялось независимо, и компилятор мог векторизовать цикл.
