To assess the performance of universities, we decided to compile a rating. The activity of the university is evaluated by an integer from −100 to 100.
Count the number of universities with a positive rating, a negative rating, and a zero rating.
The first line contains a positive integer n (1≤n≤50000) — the number of universities.
The second line contains n integers — the rating of the i (1≤i≤n)-th university.
Print three numbers in one line:
the number of universities with a positive rating;
the number of universities with a negative rating;
the number of universities with a zero rating.
