looks like there is problem with the 2nd test case result. The 'Cleve Molar' is shifted by 1 space in the ans

This problem can be trickier if the input can allow different styles of name representation, e.g., 'FirstName LastName' and 'LastName, FirstName'.

Just don't get it. In the first test case, answer is 1xN and in the second Nx1, so I just put workaround. If anyone could explain to me why this matters...

Could you explain this code please?

It's a cheat, generally used by people who can't figure out how to solve a problem with a real answer.

What is wrong with test 2? It looks the same as my output.

I initially also found that strange. But later I found out the cell structure is different. N by 1 OR 1 by N problem.

Is there a bug in the Test Suite ? I made a code that resulted in the exact ideal answer but the Test has failed!?

Adam Becker on 19 May 2019

I experienced the same thing...was able to generate the output exactly but received a failing score. Did you solve your issue?
