Today, Mezo is playing a game. Zoma, a character in that game, is initially at position $x = 0$. Mezo starts sending $n$ commands to Zoma. There are two possible commands:  'L' (Left) sets the position $x: =x - 1$;  'R' (Right) sets the position $x: =x + 1$. 

Unfortunately, Mezo's controller malfunctions sometimes. Some commands are sent successfully and some are ignored. If the command is ignored then the position $x$ doesn't change and Mezo simply proceeds to the next command.

For example, if Mezo sends commands "LRLR", then here are some possible outcomes (underlined commands are sent successfully):   "LRLR" — Zoma moves to the left, to the right, to the left again and to the right for the final time, ending up at position $0$;  "LRLR" — Zoma recieves no commands, doesn't move at all and ends up at position $0$ as well;  "LRLR" — Zoma moves to the left, then to the left again and ends up in position $-2$. 

Mezo doesn't know which commands will be sent successfully beforehand. Thus, he wants to know how many different positions may Zoma end up at.


-----Input-----

The first line contains $n$ $(1 \le n \le 10^5)$ — the number of commands Mezo sends.

The second line contains a string $s$ of $n$ commands, each either 'L' (Left) or 'R' (Right).


-----Output-----

Print one integer — the number of different positions Zoma may end up at.


-----Example-----
Input
4
LRLR

Output
5



-----Note-----

In the example, Zoma may end up anywhere between $-2$ and $2$.
