$1 \leq N \leq 10^5$ $1 \leq P \leq 100$ $0 \leq a_i \leq 100$ $(1 \leq i \leq N)$ All values in input are integers.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 $2$.
