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.
x=input()
y=input()
# v=[]
v=list(x.replace(""," "))
l=list(y.replace(""," "))
# v.append(x)
v.reverse()
m=int((len(v)-1)/2)
for i in range(0,m):
   if l[2*i+1] in v:
    print("yes")
    break
   else:
    print("no")  
    break
