Problem type

You are working at an amusement park roller coaster. There is a line of N incoming children. However, each person needs to be at least height H_{min} and at most H_{max} for safety reasons. Given the heights of each child, h_1, h_2, \dots, h_N, count the number of children who can go on the ride. N, H_{min}, H_{max}, h_i are natural numbers.


In all tests,
1 \le N \le 10^5
1 \le H_{min} \le H_{max} \le 10^6
1 \le h_i \le 2 \times 10^6
