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.

    for i in arr:
        sting.append(i)

    stin.reverse()
    count=0
    if len(stin)==len(sting):
        for i in range(len(stin)):
            if stin[i]==sting[i]:
                count+=1

    if count==len(stin):
        print("YES")
    else:
        print("NO")
