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>

int main(void)
{
   char a[3];   
   char b[3];
   scanf("%s",&a);
   scanf("%s",&b);
   if(a[1] = b[0])
   {
    if(a[0] == b[2] && a[2] == b[0])
        printf("Yes\n"); 
    else printf("No\n");
   }
   else
   {
      printf("No\n");
   }
   return 0;
}
