At some university, applicants passed a preliminary test, according to the results of which they can be admitted to the entrance exams in the first stream. Testing is carried out in two subjects. For each subject, an applicant can score from 0 to 100 points. At the same time, applicants who have scored at least 30 points in each of the two subjects according to the test results are allowed to take exams in the first stream.
The input of the program is information about the results of preliminary testing. It is known that the total number of test participants does not exceed 500.
The first line contains the number of applicants who took part in the test, N. This is followed by N lines with the following format:
