Problem Statement

N friends of Takahashi has come to a theme park.

To ride the most popular roller coaster in the park, you must be at least K centimeters tall.

The i-th friend is h_i centimeters tall.

How many of the Takahashi's friends can ride the roller coaster?

Constraints

1 \le N \le 10^5

1 \le K \le 500

1 \le h_i \le 500

All values in input are integers.

Input

Input is given from Standard Input in the following format:

N K
h_1 h_2 \ldots h_N

Output

Print the number of people among the Takahashi's friends who can ride the roller coaster.

Sample Input 1

4 150
150 140 100 200

Sample Output 1

2

Two of them can ride the roller coaster: the first and fourth friends.

Sample Input 2

1 500
499

Sample Output 2

0

Sample Input 3

5 1
