For the article Memory-Mapped-Shared-DB-Problem, the backend implementation does not respect the test cases displayed on the interface; for both the test cases, key1, key2 and nonexistent are the keys used to invoke the get() function.

get function:
std::optional<std::string> get(const std::string& key) {
std::cout << key << ':';
if (__cache__.count(key)) {
return std::string(records[__cache__[key]].value);
}
return std::nullopt;
}
Results:
