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 is_reverse_same(s, t):
    reversed_t_list = reversed(list(t))

    same_count = 0
    for index, val in enumerate(reversed_t_list):
        if index <= len(s) - 1:
            if val == s[index]:
                same_count += 1

    if same_count == len(s):
        return "YES"
    return "NO"


def main():
    s = input()
    t = input()
    result = is_reverse_same(s, list(t))
    print(result)

main()
