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

Haha, it took me a couple of minutes to fully understand that it was the vector's element length and not the vector's magnitude that was needed. -.-'
