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.
def inverso(t):
    inverso_t = ''
    quant_t = len(t)
    for letra in range (quant_t-1, -1, -1):
        inverso_t += t[letra]
    if inverso_t == s:
        return 'YES'
    else:
        return 'NO'

s = str(input(''))
t = str(input(''))      
print(inverso(t))
