#include <iostream>
#include <vector>

int main(void)
{
    std::string s = "432b2b2050726f67";
    
    size_t len = s.length();
    
    std::vector<std::string> v;
    
    for(size_t i = 0; i < len; i += 2) {
        v.push_back(s.substr(i, 2));
    }

    for (const auto &str : v) 
        std::cout << str << " ";   
        
    return 0;
