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 main():
    first = input()
    second = input()
    if len(first) != len(second):
        print("NO")
    else:
        index = 0
        diff = False
        while index <= len(first) - 1:
            if first[index] != second[len(second) - 1 - index]:
                diff = True
                break
            index += 1
        if diff == False:
            print("YES")
        else:
            print("NO")
main()
