Hello, Andriy Kavetsky. The tolerance in test 2 of the Test Suite is quite strange. As written, it seems that a result that is 1000 times larger than the true answer would be accepted as adequate. See Problem 44690 & Problem 44691 for some alternative cues. Also, it is recommended that at least four cases be provided in a Test Suite, though more are often necessary to prevent hard-coded workarounds. —DIV
