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 func():
    print("Enter first string:")
    s = str(input())
    print("Enter second string:")
    t = str(input())
    
    if len(s)!=len(t):
        return "NO"
    else:
        lo = 0
        hi = len(s)-1
        flag = 0
        while lo!=len(s) and hi!=-1:
            if s[lo]==t[hi]:
                lo+=1
                hi-=1
            else:
                return "NO"
        return "YES"
