Satre has finally decided to put their famous Letter Cookies back on market again. Of course they are just as interesting to play with as to eat. Your little sister is trying to make words out of the letters she found in the box, but you want to be faster than her to decide whether it is possible to make the word or not.
Given the letters in the cookie box, is it possible to spell out the words your little sister knows how to spell? (After creating a word, she scrambles the cookies again and can reuse the letters for later words.)
