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.
