Shouldn't the solution for n=-1 be NaN, rather than 'NaN' which is a character array?
I agree with Ken , we expect NaN and not the string 'NaN'
I believe you should also change the assert for the case n=-1 to be isequalwithnan, since isequal(NaN,NaN) is false.
yeap you have just rescored the problem but you need to use isequalwithnan,
actually you need to use isequalwithequalnans
tests 5 and 6 does not work properly. those numbers are out of precision, and for test 6 it couldn't be fixed even with uint64 used instead of type double
This problem is simply wrong. The right answer is
if we where to sum ALL the grains on the board....
