#include <iostream>
#include <map>

int main() {
    std::map<int, std::string> myMap;
    myMap[1] = "One";
    myMap[2] = "Two";
    myMap[3] = "Three";

    for (auto it = myMap.begin(); it != myMap.end(); ++it) {
        std::cout << "Key: " << it->first << ", Value: " << it->second << std::endl;
