input: Write a function to take two matrices, A and B, and produce a matrix C where each element is the product of the corresponding elements of A and B. If the matrices are not of the same dimensions, return "Matrix multiplication not possible".
  assert elementWiseProduct([[3, 4], [1, 2]], [[7, 5], [0, 1]])==[[21, 20], [0, 2]]
  assert elementWiseProduct([[1, 2], [3, 4]], [[5, 6], [7, 8]])==[[5, 12], [21, 32]]
  assert elementWiseProduct([[1, 2, 3], [4, 5, 6]], [[1, 2], [3, 4]])=="Matrix multiplication not possible"
  assert elementWiseProduct([], [])==[]
  assert elementWiseProduct([[1, 2]], [[3], [4]])=="Matrix multiplication not possible"
output: def elementWiseProduct(A, B):
