```

This example demonstrates a simple `FallbackExecutor` class that tries to execute multiple functions in sequence and provides a basic error recovery mechanism. If an exception occurs during the execution of any function, it catches the exception and continues with the next function in the list. The provided example uses three simple arithmetic functions: multiplication, addition, and subtraction.
