The evil Ruby overlord has taken you hostage. He agrees to let you go, but only if you are able to solve his puzzle:

Write me a Ruby program that reads a string $s$ from STDIN, and outputs its length to STDOUT. You can only use symbolic characters in your code (!"#$%&'()*+,-./:;<=>?@[\]^_`{|}~). In addition, your source code must be as short as possible.

Note: You may only submit to this problem in Ruby.

Input Specification

The first line of input contains a single string $s$ $(1\le |s|\le 100)$. You may assume that $s$ only contains printable characters.

Output Specification

Output on a single line, the length of $s$.

Scoring

Your score will be computed based on the length of your source code, the shorter the better. For an $L$-byte program,

• if $L\le 20$, you will receive the full $100$ points.
• if $21\le L\le 23$, you will receive $80-10\times (L-21)$ points.
• if $24\le L$, you will receive $\lfloor 2^{0.1(80-L)}\rfloor$ points.

Sample Input

Hello, World!
