CHOOSE YOUR COMPILER

Reproduce this code, choosing one of the compilers below (don't copy and paste! It would be too easy). They all have the same function, just choose one according to your preferences.

When copying your code, replace the existing (default) code already in the compiler with your own.

Warning ! Choose the compiler based on the formatting (e.g., with or without HTML tags). For some of these compilers, you must choose the programming language yourself from the menu that is then offered. Of course, don't forget to click on RUN !
