#include <bits/stdc++.h>
using namespace std;
string s,t;
int main() {
cin>>s>>t;
if(s[0]==t[2] && s[1]==t[1] && s[2]==t[0]) {
	cout<<"YES"<<endl;
} else {

}
}

### Prompt

Create a solution in Cpp for the following problem:

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.
