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<stdio.h>

int main()
{
    char s1[100],s2[100],s3[100];
    int len,i,j;
    gets(s1);
    gets(s3);
    len=strlen(s1);
    for(j=0,i=len-1; i>=0; i--,j++)
    {
        s2[j]=s1[i];
    }
    if(strcmp(s2,s3)==1)
        printf("YES\n");
    else
        printf("NO\n");
    return 0;
}
