이거 문제 설명에는 line 1, line 2, line 3 로 나뉘어 있는데 예시에서는 한줄에 다 입력되네요. 어떤거가 옳은건가요? 햇갈리네용 ㅎㅎ The question describes the coordinates are read from lines 1,2,and 3; however, the sample input shows all the coordinates being read from a single line. Could you please explain which is the correct method? ThankYou
