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.
r = str(input())
g = str(input())

if r == g[::-1]:
  print('Yes')
else:
  print('No')
r = str(input())
g = str(input())

if r == g[::-1]:
  print('YES')
else:
  print('NO')
