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.
s  = input()
t = input()
if(len(s)<=100 and len(t)<=100):
    if(len(s)==len(t)):
        t_len = len(t)
        check = True
        for i in range(len(s)):
            if(s[i]!=t[(t_len-1)-i]):
                check = False

        if(check):
            print("YES")
        else:
            print("NO")
                
    else:
        print("NO")
