Description

The translation from the Berland language into the Birlandlanguage is not an easy task. Those languages are very similar: aberlandish word differs from a birlandish word with the samemeaning a little: it is spelled (and pronounced) reversely. Forexample, a Berlandish word code corresponds to aBirlandish word edoc. However, it's easy to make amistake during the «translation». Vasya translatedword s from Berlandishinto Birlandish as t. Help him: find out if hetranslated the word correctly.

Input

The first line contains word s, the secondline contains word t. The words consist of lowercaseLatin letters. The input data do not consist unnecessary spaces.The words are not empty and their lengths do not exceed 100symbols.

Output

If the word t is aword s, written reversely,print YES,otherwise print NO.

Sample Input

Input

code

edoc

Output

YES

Input

abb

aba

Output

NO

Input

code

code

Output

NO

解法一：普通匹配

#include<iostream>
using namespace std;
int main()
{
        char a[101],b[101],c[101];
        int k,count;
        while(scanf("%s %s",a,b)!=EOF)
        {   
                count=0;
                k=strlen(a);
            strcpy(c,strrev(b));
                for(int i=0;i<k;i++)
                {
                        if(c[i]==a[i])
                                count++;
                }
                if(count==k) printf("YES\n");
                else printf("NO\n");
        }
        return 0;

解法二：利用STL中的倒置函数 strrev

#include<iostream>
using namespace std;
int main()
{
      char str2[102],str1[102];
          while(cin>>str1>>str2)
          {
             if(strcmp(str1,strrev(str2))==0)
                         cout<<"YES"<<endl;
                 else
                         cout<<"NO"<<endl; 
          }
  return 0;
