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!
