Implement the function

The function receives two arrays of the given size, having integers between 0 and 9 in each position, so that the whole array represents a number. It should return a different array, allocated by the function, containing the product of the two numbers, stored in the same way than the arguments it receives. The result should contain 2 × size digits, using leading zeroes when needed. Consider 1 ≤ size ≤ 100.

For example, for these input arguments

your function should return
