Task DOBRA

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 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.

Input

Output

The first and only line of output should cotain a single integer - the total number of plesant words that can be formed by substituing underscores with uppercase letters of the english alphabet.

Warning: Use 64 bit number formats. long long in C/C++, int64 in Pascal.
