You are given a grid with 2 rows and 3 columns of squares. The color of the square at the i-th row and j-th column is represented by the character C_{ij}.  Write a program that prints `YES` if this grid remains the same when rotated 180 degrees, and prints `NO` otherwise.
s = input()
t = reversed(input())
if(s == t):
  print("YES")
else:
  print("NO")
s = input()
t = input()
if(s == t[::-1]):
  print("YES")
else:
  print("NO")
