In this kata you will have to modify a sentence so it meets the following rules:

convert every word backwards that is:

    longer than 6 characters

  OR

    has 2 or more 'T' or 't' in it

convert every word uppercase that is:

    exactly 2 characters long

  OR

    before a comma

convert every word to a "0" that is:

    exactly one character long
 

 NOTES: 

      Punctuation must not be touched. if a word is 6 characters long, and a "." is behind it,
      it counts as 6 characters so it must not be flipped, but if a word is 7 characters long,
      it must be flipped but the "." must stay at the end of the word.
      -----------------------------------------------------------------------------------------
      Only the first transformation applies to a given word, for example 'companions,'
      will be 'snoinapmoc,' and not 'SNOINAPMOC,'.
      -----------------------------------------------------------------------------------------
      As for special characters like apostrophes or dashes, they count as normal characters, 
      so e.g 'sand-colored' must be transformed to 'deroloc-dnas'.
