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

Solution in C (GCC 5.4.1) (judge verdict: Accepted)

#include <stdio.h>

int main(void)
{
  int num;
  scanf("%d", &num);
  int numCopy = num;
  int numReverse = 0;
  int tmp;
  while (numCopy != 0)
  {
    tmp = numCopy % 10;

    numCopy = numCopy / 10;

    numReverse = numReverse * 10 + tmp;
  }

  if (num == numReverse)
  {
    printf("Yes\n");
  }
  else
  {
    printf("No\n");
  }

  return 0;
}
