    For example, if the input is "001", what should be returned? or what should be returned with "123000004"?

    01 is a invalid decode. so is 001, 0001...

    So if there is 0 in string, it can only be the zero of 10 and 20.

    As for 001 and 123000004, the output of them are 0, because no valid decode ways for them.
