We want to catch logic_error instead of std::out_of_range when dealing with stoll.
This is because stoll may throw two different errors:

• https://en.cppreference.com/w/cpp/error/invalid_argument
• https://en.cppreference.com/w/cpp/error/out_of_range

Both of them inherit from logic_error https://en.cppreference.com/w/cpp/error/logic_error

You may want to intentionally trigger each of these errors and see if the code catches them.
