Problem Statement

You are given a three-digit positive integer N.

Determine whether N is a palindromic number.

Here, a palindromic number is an integer that reads the same backward as forward in decimal notation.

Constraints

100≤N≤999

N is an integer.

Input

Input is given from Standard Input in the following format:

N

Output

If N is a palindromic number, print Yes; otherwise, print No.

Sample Input 1

575

Sample Output 1

Yes

N=575 is also 575 when read backward, so it is a palindromic number. You should print Yes.

Sample Input 2

123

Sample Output 2

No

N=123 becomes 321 when read backward, so it is not a palindromic number. You should print No.

Sample Input 3

812

Sample Output 3

No

#include <stdio.h>
int main(void)
{
    char a[100];
    int c=0;
    int flg=1;
    int i,j;
    scanf("%s", a);
    for(i=0;a[i]!='\0';i++){
        c++;
    }
    for(i=c-1,j=0;i>=0,j<c;j++,i--){
        if(a[j]!=a[i]){
            flg=0;
            break;
        }

    }
    if(flg==1){
        printf("Yes");
    }else{
        printf("No");
    }
}
