Score : $200$ points
$N$ 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.
Input is given from Standard Input in the following format:
$N$ $P$ $a_1$ $a_2$ $\dots$ $a_N$
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 $2$.
