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

Solution in C (GCC 5.4.1) (judge verdict: Wrong Answer)

#include <stdio.h>
#include <string.h>

int main(void){
	
	char in[2][3];
	int i,j;
	char tmp = 0;
	
	for(i=0;i<2;i++){
		scanf("%s",in[i]);
	}
	
	
	for(i = 0, j = 2; i < 1; i++, j--){
		tmp = in[0][i];
		in[0][i] = in[0][j];
		in[0][j] = tmp;
	}
	
	if(!strcmp(in[0],in[1])){
		printf("YES\n");
	}else{
		printf("NO\n");
	}
	return 0;
