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.
The first line contains word *s*, the second line contains word *t*. The words consist of lowercase Latin letters. The input data do not consist unnecessary spaces. The words are not empty and their lengths do not exceed 100 symbols.
word = input()
translated_word = input()

word_len = len(word)
translated_word_len = len(translated_word)

translation_is_correct = True

for i in range(word_len):
    if word[i] != translated_word[translated_word_len - i - 1]:
        translation_is_correct = False

if translation_is_correct:
    print('YES')
else:
    print('NO')
