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 translation(stringA: str, stringB: str) -> str:
    
    if len(stringA) != len(stringB):
        return "NO"

    i = 0
    j = len(stringB)-1

    while i < len(stringA) and j >= 0:
        if stringA[i] != stringB[j]:
            return "NO"
        i += 1
        j -= 1

    return "YES"

def main():
    string1 = input().strip()
    string2 = input().strip()
    print(translation(string1, string2))

main()
