The translation from the Berland language into the Birland language is not an easy task. Those languages are very similar: a berlandish word differs from a birlandish word with the same meaning a little: it is spelled (and pronounced) reversely. For example, a Berlandish word code corresponds to a Birlandish word edoc. However, it's easy to make a mistake during the «translation». Vasya translated word *s* from Berlandish into Birlandish as *t*. Help him: find out if he translated the word correctly.
The first line contains word *s*, the second line contains word *t*. The words consist of lowercase Latin letters. The input data do not consist unnecessary spaces. The words are not empty and their lengths do not exceed 100 symbols.
#include <iostream>
using namespace std;

void reverseStr(string& str){
  int n = str.length();
  int i;
  for (i = 0; i < n/2; i++)
    swap(str[i], str[n-i-1]);
}


int main() {
  string x;
  string y;
  cin >> x >> y; // Get user input from the keyboard
  reverseStr(y);
  cout << y;
  if(x.compare(y) == 0){
    cout << "YES";
  } else{
    cout << "NO";
  }
}
