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.
name1=input().lower()
name2=input().lower()
c=0;
number_name2=len(name2)-1
for i in range(0,len(name1)):
    if name1[i]!=name2[number_name2]:
        c+=1
    number_name2-=1    
if c==0:
    print("YES")   
else:
    print("NO")
