Problem Statement

You are given a string S of length 2 or 3 consisting of lowercase English letters. If the length of the string is 2, print it as is; if the length is 3, print the string after reversing it.

Constraints

The length of S is 2 or 3.

S consists of lowercase English letters.

Input

Input is given from Standard Input in the following format:

S

Output

If the length of S is 2, print S as is; if the length is 3, print S after reversing it.

Sample Input 1

abc

Sample Output 1

cba

As the length of S is 3, we print it after reversing it.

Sample Input 2

ac

Sample Output 2

ac

As the length of S is 2, we print it as is.

Solution in Scala (2.11.7) (judge verdict: Accepted)

object Model {
  def getOutput(input: String) = {
    if (input.size == 2) input
    else input.reverse
  }
}

object Main extends App {
  import Model._
  val in = scala.io.StdIn
  val input = in.readLine()
  println(getOutput(input))
}
