This code defines a `FallbackExecutor` class that can be used to handle limited error recovery by providing a secondary function or re-executing the primary one. The example usage demonstrates its application in a scenario where an input might cause an error, and a fallback mechanism is employed to either recover from the error or retry the operation.
