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 <bits/stdc++.h>

using namespace std;

int main()
{
      string a,b;
      cin>>a;cin>>b;

      int i,j,k=1,l=2;;

      for(i=0;i<2;i++)
      {
         if(a[i]!=b[l]){
            k=0;
            break;
         }
          l--;
      }

      if(k==1)puts("YES");else puts("NO");
    return 0;
}
