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()
if a[::-1] == b:
    print("Yes")
else:
    print("No")

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