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==B[::-1]:
    print("Yes")
else:
    print("No")
A =input()
B =input()
if A==B[::-1]:
    print("YES")
else:
    print("NO")
