simple and smart . good job !

good job solving it in a one line . I'm looking to learn this way of solving so you have an idea of what to search for on youtube?

I have the same issue . I don't even know what are te other test cases

I failed only one test , i spent two hours thinking why this test has been failed but no hope . I even tried to debug it !

Something wierd going on when I click submit .
I already tested all cases and everything is fine . but when I click submit it's showing me failed weird test cases that are not there .
