input: Write a function to take two matrices A and B, and return a matrix C where each element of C is the product of the corresponding elements of A and B. If the matrices do not have the same dimensions, return a message stating that element-wise multiplication is not possible.
  
  assert matrixElementwiseProduct([[3, 4], [1, 2]], [[7, 5], [0, 1]]) == [[21, 20], [0, 2]]
  assert matrixElementwiseProduct([[2, 3], [4, 5]], [[1, 2], [3, 4]]) == [[2, 6], [12, 20]]
  assert matrixElementwiseProduct([[1, 2]], [[3], [4]]) == "Element-wise multiplication not possible"
  assert matrixElementwiseProduct([[1]], [[2]]) == [[2]]
output: def matrixElementwiseProduct(A, B):
      if len(A) != len(B) or any(len(rowA) != len(rowB) for rowA, rowB in zip(A, B)):
          return "Element-wise multiplication not possible"
      return [[A[i][j] * B[i][j] for j in range(len(A[0]))] for i in range(len(A))]
