    size_t len = s.length();
     
    std::vector<unsigned int> v;
     
    for(size_t i = 0; i < len; i += 2) {
        unsigned int n;   
        std::stringstream ss;
        ss << std::hex << s.substr(i, 2);
        ss >> n;
        
        v.push_back(n);
    }
 
    for (const auto &i : v)
