Few day ago i found out that i still didn't finish this task. So i try to do it and i don't know why but this task doesn't work. I don't get any detalied information about verification of my program right here and also on IntelliJ... I don't know what is going on. A few minutes ago i finish another tasks and it's working fine i have information why my solution didn't pass the verification.
