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,b=[input() for _ in range(2)]
print("Yes" if a == b[::-1] else "No")
a,b=[input() for _ in range(2)]
print("YES" if a == b[::-1] else "NO")
