input: Write a python function to multiply corresponding elements of two arrays.
  assert multiply_arrays([1, 2, 3], [4, 5, 6]) == [4, 10, 18]
  assert multiply_arrays([2, 3, 4], [1, 0, -1]) == [2, 0, -4]
  assert multiply_arrays([0, 0, 0], [1, 2, 3]) == [0, 0, 0]
output: def multiply_arrays(arr1, arr2):
      return [a * b for a, b in zip(arr1, arr2)]
