Problem:
Score : 100 points

Problem Statement

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}

Output

Print YES if this grid remains the same when rotated 180 degrees; print NO otherwise.

Sample Input 1

pot
top

Sample Output 1

YES

This grid remains the same when rotated 180 degrees.

Sample Input 2

tab
bet

Sample Output 2

NO

This grid does not remain the same when rotated 180 degrees.

Sample Input 3

eye
eel

Sample Output 3

NO

import java.util.Scanner;

public class Main {
	public static void main(String[] args) {
		Scanner scanner = new Scanner(System.in);
		String s1 = scanner.nextLine();
		String s2 = scanner.nextLine();
		
		char[] check = s2.toCharArray();
		char[] reverse = new char[s2.length()];
		
		for (int i = 0; i < reverse.length; i++) {
			reverse[i] = check[check.length-i-1];		
		}
		String rString = new String(reverse);
		if (rString.equals(s1)) {
			System.out.println("Yes");
		}else{
			System.out.println("No");
		}
		
		scanner.close();
	}
