Write a function that takes as input vectors "r" and "y" of length n and m, respectively, and returns the following matrix: x[1] * y[1] x[1] * y[2] .. x[1] * y[m] x[2] * y[1] [2] * y[2] x[2] * y[m] x[n] * y[1] [n] * y[2] x[n] * y[m] Execute your function on input vectors x= [1,2,3,4] and y= [5,6,7,8,9,10)
