Explanation
The output panel will display "Hello World" because the workflow is designed to first display "Hello" and then "World" in the output panel. The workflow starts with an Assign activity that initializes the Boolean flag to True. Then, the While activity checks if the flag is True. If it is, the workflow enters the Body section of the While activity. Inside the Body section, the workflow checks if the flag is True. If it is, the workflow enters the Then section of the If activity and displays "Hello" in the output panel. Then, the Assign activity sets the flag to False. Since the flag is now False, the workflow enters the Else section of the If activity and displays
"World" in the output panel. Finally, the workflow exits the While activity since the flag is now False.
