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 Go (1.6) (judge verdict: Accepted)

package main

import (
  "fmt"
)

func reversedString(s string) string {
  r := []rune(s)
  n := len(r)
  for i := 0; i < n / 2; i++ {
    r[i], r[n-1-i] = r[n-i-1], r[i]
  }
  return string(r)
}

func main() {
  var n string; fmt.Scan(&n)
  ans := "No"
  if n == reversedString(n) {ans = "Yes"}
  fmt.Println(ans)
}
