This code defines a class `FallbackExecutor` that can be used to create a fallback mechanism for functions. The class is initialized with the main function and an optional backup function, as well as exception types that should trigger the fallback. The `execute` method attempts to run the primary function; if it raises one of the specified exceptions, it tries running the backup function instead. An example usage demonstrates how to use this class in a situation where division by zero might occur.
