816. Ambiguous Coordinates

We had some 2-dimensional coordinates, like "(1, 3)" or "(2, 0.5)". Then, we removed all commas, decimal points, and spaces and ended up with the string s. - For example, "(1, 3)" becomes s = "(13)" and "(2, 0.5)" becomes s = "(205)". Return a list of strings representing all possibilities for what our original coordinates could have been. Our original representation never had extraneous zeroes
