| Aug 15 at 9:56 | comment | added | TorbenPutkonen | Just for curiosity, regarding the industry standard practices: Arrays.stream(source).parallel().sum(); does everything you need. Maybe add asLongStream() to reduce the amount of integer over/underflows. | |

(omitting this is not an option) 1) What does "There is no concurrency?" mean? 2) What does "(Maximum) modulo value of each array element" mean?) | |

@greybeard: I solved the first mystery: searching on "modulus" found the comment on the definition of MAX_VALUE_FOR_RANDOM. So apparently they're assuming that random.nextInt(MAX_VALUE_FOR_RANDOM) is implemented internally as random % maxval, instead of a method which avoids introducing bias for ranges which aren't powers of 2. (And this assumption is present even in the assignment. Yikes.)
