This is a car. That is a pen. This is a car. This is a car.
This is a car. That is a pen. This is a car.
The first and third sentence in the inputting text are the same and there is no duplicates in the output text. The first and fourth sentence in the inputting text looks similar but there are two spaces between "is" and "a" in the fourth sentence. So those are different and the fourth sentence is not deleted. This program doesn't change the order of sentences.
