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.
try:
    def f(l1,l2):
        if(len(l1)!=len(l2)):
            return "NO"
        else:
            rev=""
            for i in l2:
                rev=i+rev
            if rev==l1:
                return "YES"
            return "NO"
            
    l1=input()
    l2=input()
    print(f(l1,l2))
except:
    pass
