题目描述

As we all know that RXD is a life winner, therefore he always goes out, dating with his female friends.
Nevertheless, it is a pity that his female friends don't like extremely hot temperature. Due to this fact, they would not come out if it is higher than 35 degrees.
RXD is omni-potent, so he could precisely predict the temperature in the next t days, but he is poor in counting.
He wants to know, how many days are there in the next t days, in which he could go out and date with his female friends.
