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()

if (c1[0] == c2[2] and c1[1] == c2[1]) and c1[2] == c2[0]:
    print("Yes")
else:
    print("NO")

c1 = input()
c2 = input()

if (c1[0] == c2[2] and c1[1] == c2[1]) and c1[2] == c2[0]:
    print("YES")
else:
    print("NO")
