CodeFu Shortest Solution Rules

The rules of the Shortest Solution Competition are very simple.

Solutions are rated according the non blank characters.
Blanks, tabs, newline characters are not counted.

The number of characters of the correct solution are substracted from 500 to get the score.

E.g. If a solution has 192 non blank characters, the solution gets 500-192=308 points.

The solution gets the points only if it passes ALL 100 test cases.
