And it throws "Can't read or parse problem descriptor" for me in virual contest.

I'm still investigating this task and here what I have:

• submission with EPS = 1e-14 gives wrong answer on test #134: 200.0 200.0 200.0: 15719829,

• the same code with EPS = 1e-13 gives AC: 15719618.

I've logged the difference between two values of m * log(m) + log(log(m)) for m = 200.0 in first case and it appears to be ~5e-14, so this is the reason. But when I'm trying to reproduce this problem manually (see main at 15719829), it is giving zero difference. On my mac with clang 6.0 compiler case 200.0 200.0 200.0 gives proper answer: x^y^z. Can anyone help?

Sorry, I accidentally click "Discard" button. Now it is recovered. Peace.
