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.
import sys

x = input()
y = input()

if x == reversed(y):
    print("YES")
else:
    print("NO")
import sys

x = input()
y = input()

if x == y[::-1]:
    print("YES")
else:
