It was a crummy day for Lur. He failed to pass to the CET-6 (College English Test Band- 6 ). Looking back on how it was in last year gone by, he gradually noticed he had fled too many English Lessons. But he determines to memorize words on his bed ,not in the classroom. You know, it is not that easy to pass the test mainly because the large amount of born words.

Lur is intelligent on games , never English. He cann't learn the similar words by heart. He always choose to select a word to learn from the similar words . For him, two words are similar if and only if one word can equal to the other by multiple cyclic shift(at least 1 ). For example, car and arc are similar words, while car and rca are also similar words . To save more time to play games.

Lur want to know wether two words are similar words faster, he asks you to write a program to tell him ,can you help him ?
