```

This code defines a `FallbackExecutor` class that allows you to specify a primary function and one or more fallback functions. It then tries to execute the primary function first; if it fails, it attempts each fallback in order until one succeeds. The example usage demonstrates adding multiple fallbacks and executing them with an input value.
