It was added to the `Main` class to demonstrate the usage of the `reverseWords` method. The `testReverseWords` method takes two parameters: the input string and the expected output string. It calls the `reverseWords` method to get the actual output and compares it with the expected output. If they match, it prints \"Test Passed: Yes\"; otherwise, it prints \"Test Passed: No\".",
