Strange - the test suites are not independent. I thought they normally were.

Sushovan Basu on 8 Dec 2017

Yes Andrew, they are not. I also had to struggle with the same, when only the first input data passed and rest failed.

Christian Torregrosa Koch on 14 Dec 2017

I can't get a way to solve this problem. Some hint?

Hans Kramer on 25 Apr 2018

Can't solve this either. Not even a clue on how to do it.

Hint see documentation for presistent variables
PS : last test case is evil
