Write code to multiply an array x by a matrix y.
Array x has size of 1xn, while matrix y has size of nxn,
so the result is a 1xn array.
Your function should call another function multiply () that multiplies two arrays and return a value
(e.g. copy function from problem 3 of assignment 3).
Hint: You will also need to call your transpose( ) function from problem 1 to transpose the y matrix for correct result.
Remember to include ../problem-1/main.h for that.
Edit the multiply( ) function in the main.cpp file.
The function takes x, y, and n as input and returns the result array as the output.
Do not write a main function. Only edit the part marked with
// Write your code here
