Lea runs into a lot of words in her life. A lot of them she finds unpleasant. To compensate for that she started making up plesant words. Lea makes up new words by writing a nice looking string of characters on a piece of paper. She than erases a few of the most nasty looking characters and replaces them with underscores '_'. After that she tries to replace the underscores with more acceptable characters trying to form a plesant word.

Lea considers words plesant if they do not contain 3 sequential vowels, 3 sequential consonants and contain at least one letter 'L'.

In Croatian vowels are letters A, E, I, O, U only. All other lettters are consonants.
