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.
# check if input a ( code ) is revesly = to input b (edoc)
my_list = []

for _ in range(2):
    user_input = input()
    my_list.append(user_input)


reversed_word = my_list[1]
if my_list[0] != reversed_word[::-1]:
    print('NO')

elif my_list[0] == reversed_word[::-1]:
    print('YES')



# print(my_list)
# print(my_list[::-1])
# print(my_list[1].reversed())
# if my_list[0] == my_list[1::-1]:
#     print(True)
