The p-norm of a vector v = (v₁,v₂, . . . ,v_n) in n-dimensional space is defined as

For the special case of p = 2, this results in the traditional Euclidean norm, which represents the length of the vector. For example, the Euclidean norm of a two-dimensional vector with coordinates (4,3) has a Euclidean norm of ˆš4²+3² = ˆš16+9 = ˆš25 = 5. Give an implementation of a method named norm such that norm(v, p) returns the p-norm value of v and norm(v) returns the Euclidean norm of v, where v is represented as an array of coordinates.

|M|= V* +v3 + .+v%. 9
