`using namespace std;` is generally an antipattern as it imports a huge number of common names into the global namespace. We already qualify names with std:: in majority of cases and `using namespace std` is not actually needed most of the time. This commit addresses a small number of remaining cases where std:: is missing and removes all `using namespace std`, thus achieving consistent code.
