Scalar product P71310

Statement

thehtml

The scalar product of two vectors u=(u₀,…,u_n−1) and v=(v₀,…,v_n−1) is ∑_i=0ⁿ⁻¹ u_i v_i.

Write a function that returns the scalar product of u and v.

Interface

C++	double scalar_product(const vector<double>& u, const vector<double>& v);
C	double scalar_product(int n, double u[n], double v[n]);
Java	public static double scalarProduct(double[] u, double[] v);
Python	scalar_product(u, v) # returns float
MyPy	scalar_product(u: list[float], v: list[float]) -> float

Precondition

The vectors u and v have the same size.

Observation You only need to submit the required procedure; your main program will be ignored.
