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.
# Tasks
# - Create a script to `WORDLIST` problem using the .in and .out files
# - IMPLEMENT ROT13, ROT47, ETC...
# - Implement combinations(arr, r) -> returns all possible combinations or a generator
# --------------------
# 158 B - Taxi
# n = int(input())
# A = list(map(int, input().split()))
# A.sort(reverse=True)
# count = 0
# # write your greedy code here...
# print(count)
# --------------------
print('YES' if input()[::-1]==input() else 'NO')
