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 <iostream>
using namespace std;
 
int main()
{
  char mat[3][4];
  int i,j;
  for(i=0;i<2;++i)
  {
    for(j=0;j<3;++j)
    {
      cin>>mat[i][j];
    }
  }
  
  if((mat[0][0]==mat[1][0]) && (mat[0][1]==mat[1][1]) && (mat[0][2]==mat[1][0]))
       printf("YES");
  
  else
    printf("NO");
