Time Limit: 2000/1000 MS (Java/Others)

Memory Limit: 524288/524288 K (Java/Others)

## Description

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.

## Input

There is only one test case.

The first line consists of one integer $t$.

The second line consists of $t$ integers $c_i$ which means the temperature in the next $t$ days.

$1\leq t\leq 1000$

$0\leq c_i\leq 50$

## Output

Output an integer which means the answer.
