B - Failing Grade

Score : $200$ points

Problem Statement

$N$ students took an exam. The students are labeled as Student $1$, Student $2$, $\dots$, Student $N$, and Student $i$ scored $a_i$ points.

A student who scored less than $P$ points are considered to have failed the exam and cannot earn the credit. Find the number of students who failed the exam.

Constraints

• $1 \leq N \leq 10^5$
• $1 \leq P \leq 100$
• $0 \leq a_i \leq 100$ $(1 \leq i \leq N)$
• All values in input are integers.

Input

Input is given from Standard Input in the following format:

$N$ $P$

$a_1$ $a_2$ $\dots$ $a_N$

Output

Print the number of students who failed the exam.

4 50
80 60 40 0

Students $1$ and $2$, who scored $80$ and $60$ points, respectively, succeeded in scoring at least $50$ points to earn the credit.
On the other hand, Students $3$ and $4$, who scored $40$ and $0$ points, respectively, fell below $50$ points and failed the exam. Thus, the answer is $2$.
