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.
def main():
   s = input() 
   t = input() 
   vex = list(t) 
   vex.reverse() 
   t = ''.join(map(str, vex))
   #print(t)
   if t ==s:
       print('YES') 
   else:
       print('NO')

if __name__=='__main__':
        main()
