I am getting the answer but the order of elements in my vector doesn't match the required answer. How can I get it in the required order?

I do not understand why this code failed assertion test even though it yields the correct answer

function mpg = sort_cars(N)
load cars.mat
sorted = sortrows (cars,4)
n = N
mpg = sorted(1:n,2)
end
