The explanation of this problem is a bit confusing. It can mean, that one should compute the length of the array itself or the length of a vector in a coordinate system. I saw what was meant looking at the tests. But before I was confused.

able to find the length using x = vector but code did not give the output the problem wanted

Not clear whether the problem is asking for the geometric length (norm) or number of elements.

you are right, the author should rephrase the description....
