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 reverse(s):
    str = ""
    for i in s:
        str = i + str
    return str
c=str(input())
x=str(input())
i=0
a=0
g=reverse(x)
for i in range(len(c)):
  
   
    if(c[i]==g[i]):
        a+=1
        continue
        
    else:
        print("NO")
        break
    
    i+=1

if(a==len(c)):
    print("YES")
