Difficulty—

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. ## Constraints * $C_{i,j}(1 \leq i \leq 2, 1 \leq j \leq 3)$ is a lowercase English letter. ## Input Input is given from Standard Input in the following format: $C_{11}C_{12}C_{13}$ $C_{21}C_{22}C_{23}$ [samples]
