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

package main

import (
    "bufio"
    "fmt"
    "os"
)

var sc = bufio.NewScanner(os.Stdin)

func nextLine() string {
    sc.Scan()
    return sc.Text()
}

func main() {
    a := nextLine()
  	var b string
  	for i := 0; i < len(a); i++ {
    	var tmp int = len(a) - i - 1 
    	b += string(a[tmp])
	}
  
  if a == b { 
  	  fmt.Println("Yes") 
  } else { 
  	  fmt.Println("No") 
  }
  
}
