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, it's easy to make a mistake during the «translation». Vasya translated word s from Berlandish into Birlandish as t. Help him: find out if he translated the word correctly.
从Berland语言到Birland语言的翻译工作可不简单，这两种语言非常类似，但拼写却正好相反，比如code翻译为edoc。Vasya将词语s按这种规则翻译为t，请你帮忙看一下他是否翻译正确。
