String Calculator Code Kata

You will write a string calculator. It will process strings like "1,1", add the numbers up, and return results like "2". Use the scaffolding that is already in place. Here are some example calculations your system should perform:

• "" => 0
• "1" => 1
• "1,1" => 2
• "1,2,3" => 6

After this, try adding the following:

• The string can specify another delimiter, after two leading slashes at the start. E.g.: \\#1#1 => 2
• When the result is displayed, if it is divisible by 10, you get a smiley face as well, e.g. 5,5 => 10 :-).
• Letters are interpreted as numbers, e.g. "A" = 1, "Z" = 26

Useful Commands

Run your application:

php ./scripts/run.php calculate 1,1
