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.
a = input()
b = input()

print("YES" if a == b[-1:] else "NO")
a = input()
b = input()
 
print("YES" if a == b[::-1] else "NO")
