Problem

Boxing is a rough sport. To balance that, friendly matches follow a code of conduct that keeps the fight civil. The best known rule of that code is to never hit the opponent below the waist or above the neck.

You are given the waist height and the neck height of the opponent, together with the heights of the punches that were thrown. Count how many of those punches follow the rule. A punch is fair when its height is at least the waist height and at most the neck height.

Input

The first line contains three integers $W$ , $N$ and $P$ : the waist height of the opponent, the neck height of the opponent, and the number of punches thrown ( $1 \le W < N \le 200$ , $1 \le P \le 100$ ).

The second line contains $P$ integers $H_1, H_2, \dots, H_P$ ( $1 \le H_i \le 200$ ), the heights of the punches. All heights are given in centimetres.

Output

Print one line with the number of fair punches.
