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.
#Take the inputs
str1 = input()
str2 = input()

#if the two string has not equal length return "NO"

if len(str1) != len(str2):
	print('No')

#reverse str1

new_str1 = ''

for i in range(len(str1)-1, -1, -1):
	new_str1 += str1[i]

#check if reverted string is equal to the string two.

if new_str1 == str2:
	print('Yes')
else: 
	print('No')
