Re^3: Matching or masking specific characters in an array of strings

They're not talking about "masking away" characters from a given character set in a single string. They're talking about masking multiple strings together in order find out which characters those strings have in common. Hence:


  southern
- yourself
----------
  -ou--e--

(where - (minus) is the masking operation.)

I reckon we are the only monastery ever to have a dungeon stuffed with 16,000 zombies.
