Haven't seen it. Need to take a look at spoil before.

It's well-know trick in codegolf.

thought it was the missing return 0

"one character shorter" is important :D for short-code contests!

There's a typo: should be #pragma instead of #prama.

Chat GPT's answer to "Why is #import deprecated in C++?"

The #import directive was never actually part of the C++ language specification. Instead, it was a Microsoft-specific extension to the language that allowed developers to include type libraries in their code.

Type libraries are files that describe the interfaces of COM (Component Object Model) objects. The #import directive allowed C++ developers to automatically generate C++ classes that encapsulated the interfaces of COM objects described in a type library.

However, because the #import directive was a non-standard extension to the C++ language, it was not portable to other platforms or compilers. Additionally, the use of COM has decreased in recent years, so there is less need for the #import directive.

As a result, the #import directive has been deprecated by Microsoft in favor of using the more portable #include directive to include header files that define C++ classes and functions.
