The translation from the Berland language into the Birland language is not an easy task. Those languages are very similar: a Berlandish word differs from a Birlandish word with the same meaning a little: it is spelled (and pronounced) reversely. For example, a Berlandish word code corresponds to a Birlandish word edoc. However, making a mistake during the "translation" is easy. Vasya translated the word $*s*$ from Berlandish into Birlandish as $*t*$. Help him: find out if he translated the word correctly.
