$N$ 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: $N$ $P$ $a_1$ $a_2$ $\dots$ $a_N$ [samples]
