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.
c1 = input()
c2 = input()
c1 = c1[::-1]
if c1 == c2:
  print("Yes")
else:
  print("No")
c1 = input()
c2 = input()
c1 = c1[::-1]
if c1 == c2:
  print("YES")
else:
  print("NO")
