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

#include <stdio.h>
int main() 
{
    char array[7];
     char a, b, c, d, e, f;
    int i, j;
     j = 0;
    scanf("%s %s %s", a, b, c);
    scanf("%s %s %s", d, e, f);
   array[0] = a;
   array[1] = b;
   array[2] = c;
   array[3] = d;
   array[4] = e;
   array[5] = f;

    for (i = 0; i<=2; i++) {
       if (array[i] == array[5-i]) {
         j++;
       }
      printf("%d %d \n", array[i]), array[5-i];
    }
    
    if (j == 3) {
      printf("YES");
    } else {
     printf("NO");
     }
return 0;
