Your little brother is learning to write. He knows how to write every three-letters numbers: one, two, six and ten. But as your little brother is still young, he still makes some mistakes: sometimes, one letter is wrong. Despite that, you wish to write a program that recognizes his words. It is guaranteed that each word has a unique interpretation: your little brother is a well-behaved man, and never writes words such as "twn".
