input: Write a function to multiply two matrices, A and B, and produce a matrix C where each element in C is the product of the corresponding elements in A and B. If the dimensions of A and B are not suitable for element-wise multiplication, return "Element-wise multiplication not possible".
  assert elementWiseMultiplication([[3, 4], [1, 2]], [[7, 5], [0, 1]])==[[21, 20], [0, 2]]
  assert elementWiseMultiplication([[2, 3], [4, 5]], [[1, 0], [0, 1]])==[[2, 0], [0, 5]]
  assert elementWiseMultiplication([[1, 2], [3, 4]], [[5, 6], [7, 8]])==[[5, 12], [21, 32]]
  assert elementWiseMultiplication([[1, 2], [3, 4]], [[1], [2]])=="Element-wise multiplication not possible"
  assert elementWiseMultiplication([], [])==[]
