### 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.
