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 translate(s: str, t: str) -> str:
    
    l, r = 0, len(s)-1
    
    while l < len(s) and r >= 0:
        print(s[l], t[r])
        if s[l] != t[r]:
            return 'NO'
        l, r = l+1, r-1
    
    return 'YES'

if __name__ == '__main__':
    list_ = [] * 2
    for _ in range(len(list_)):
        list_.append(input())
    [s, t] = list_
    print(translate(s, t))
