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()
ans = 0
length = len(s)
for i in range(length):
    if t[length-1-i] == s[i]:
        ans = ans+1
if ans == length:
    print("YES")
else:
    print("NO")










































# temp = 0
# for i in range(length):
#     if s[i] != t[length - 1 -i]:
#         temp = 1
#         print("NO")
#         break
# if temp == 0:
#     print("YES")
