Parsing a std::string to a std::tuple

I'm looking to read input from a file and convert this to a std::tuple type. For example, I might have input like this:

((3,12,8),(2,4,6),(14,5,2))

in a file. Is there any built-in way to parse this to a std::tuple?

The ultimate goal is to create a minimax tree from this input, so the tree would look like . My Tree type looks something like this:

class Tree{
    int data;
    bool is_max_ply;
    vector<Tree*> children
};

Any better options on creating my tree other than using std::tuple?

Thanks!
