2. Definition: a vector v with n elements, n > 1, is increasing up to and including the k-the element if the following applies to the elements u; of v: Vi V2 = 33 Uk-1 = UK and, only in case k Vx+1 Example: the vector v = (-1.5, , 5, v29.5, 3.5, 127 , 49] is increasing up to and including the fourth element, hence k = 4. i) Define a function with input the vector v and as output the value of k for which the vector v is increasing up to and including the k-the element. You don't may use the commands break, return or continue or standard routines with the exception of length. The function must not display (any) results. ii) Test this function (on 'all' possible outcomes of k and at various values of n)<>
