给你一个分割字符串形式的数组的神器.

vector<int> getvec(string str){
    vector<int> vec;
    string temp = "";
    for(int i=0;i<str.length();++i){
        if(!isdigit(str[i])){
            if(temp.size() > 0)
                vec.push_back(toint(temp));
            temp = "";
        }
        else
            temp += str[i];
    }
    if(temp.size() > 0)
        vec.push_back(toint(temp));
    return vec;
}
