input: Write a function to compute the element-wise product of two matrices A and B, and return the resulting matrix C. Each element in C should be the product of the corresponding elements in A and B. If the matrices do not have the same dimensions, return an error message indicating that element-wise multiplication is not possible.

  assert elementWiseProduct([], []) == []
  assert elementWiseProduct([[1, 2]], [[3], [4]]) == "Element-wise multiplication not possible"
output: def elementWiseProduct(A, B):
