Marcus loves giving out hugs. Each day, there are ~N~ people that Marcus can choose to hug or not. Person ~i~ will have a cuteness value of ~v_i~. Marcus is a picky hugger, and only wishes to hug people with a positive cuteness value. Otherwise, if you have a non-positive cuteness value, he will only give you a head pat (which hurts). Can you determine how many people Marcus will hug by the end of the day?
The first line will contain the integer ~N~ ~(1 \le N \le 100)~.
The next line will contain ~N~ integers, ~v_i~ ~(-100 \le v_i \le 100)~, the cuteness value of person ~i~.
Output the number of people Marcus will hug.
5 -1 -5 3 2 0
Explanation For Sample
Only person ~3~ and person ~4~ have a positive cuteness value, so Marcus will hug only them.
