X1087: Matrix Multiplication

In math, multiplying a matrix by a single number is straightforward. For example, if you had a 2D array of ints

int [][] numbers = {
  {1, 2, 3},
  {4, 5, 6}
};

You could multiply it by 2:

{
  {2, 4, 6},
  {8, 10, 12}
}

Put simply, each value in the 2D array has been multiplied by 2.

For this method, first create a new array with the same dimensions as numbers. Then set each value in this new array to be the corresponding value from numbers multiplied by the given n. Finally, return that new array.
