Answer:
Any number less than or equal to 100 or greater than or equal to 500.
Step-by-step explanation:
The loop is running if the number is greater than 100 and the number is less than 500 both conditions needs to be true to run the while loop so if the number entered less than or equal to 100 or greater than or equal to 500 then loop will stop and hence we don't need to enter the number.
