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.

Constraints

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~

Input Specification

The first line contains three numbers separated by spaces: ~N, H_{min}, H_{max}~ the number of children in line, minimum height, and maximum height, respectively.
The second line contains ~N~ numbers separated by spaces, the height of each child: ~h_1, h_2, \dots, h_N~.

Output Specification

Output on a single line, the total number of children who can go on the roller coaster.
