This Python code defines a `ErrorMonitor` class that can be used to manage and recover from limited errors within a system. It includes methods for adding error messages and their recovery actions, checking for errors in provided data, and executing the appropriate recovery action when an error is detected. The example usage demonstrates how to use this class with two custom recovery functions.
