Compare two versions of the size.Idea: Determine the size of the corresponding interval by separating the dots. Because of the length of the problem, there are 0 of the existence, so if one to the end of the other, if not, it may be assumed that the end of the interval after the value of "0".The Stoi () function is used. If the version in the interval is the same, and it is already at the end, then it is equal. Otherwise, always judge until two versio
