Count the passing marks

Problem

A mark of 40 or more is a pass. Given the marks of a class, print how many students passed.

Input: The first line has n, the number of values. The second line has the n values separated by spaces.
Output: One integer: the number of marks that are 40 or more.
Constraints: 1 ≤ n ≤ 1000
0 ≤ each mark ≤ 100

Example

Input

4
72 35 88 41

Output

72, 88 and 41 are passes.

Try the problem first. Open one hint at a time.

Hint 1

Use a counter that starts at 0 and goes up by 1 for each mark that passes.

Hint 2

Check mark >= 40, not > 40.

Write your Python code, run it on the examples and submit it to hidden tests.
