Java Multithreading, Level 2, Lesson 13
Resolved

Don't I return the expected array of numbers?I have quite a story with this task. First, none of the requirements was met, even though the output was as expected. Then I changed the Math.pow(...) method for my own digitToThePower(long a, long b) to save time and space in memory (as I understood from the help section that might be the problem).
