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.
s = str(input('enter the word:'))
t = str(input('enter the word:'))
s = s.lower()
t  = t.lower()
if len(s)<=100:
    if len(t)<=100:
        if s[::-1] == t:
            print('YES')
        else:
            print('NO')
    else:
        print('Please word length must be less than or equal to 100 in t')
else:
     print('Please word length must be less than or equal to 100 in s')
