//This is an ArrayReverser Problem..

import java.util.Scanner;

public class Main {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
  
// Read in the list of numbers
int[] numbers;
String input = sc.nextLine();
if (input.equals("")) {
numbers = new int[0];
} else {
String[] numberStrings = input.split(" ");
numbers = new int[numberStrings.length];
for (int i = 0; i < numberStrings.length; i++) {
numbers[i] = Integer.parseInt(numberStrings[i]);
}
}
  
// Reverse the list
int[] resultArray = reverseArray(numbers);
  
// Print the reversed list
StringBuilder resultSb = new StringBuilder();
for (int i = 0; i < resultArray.length; i++) {
resultSb.append(new Integer(resultArray[i]).toString());
if (i < resultArray.length - 1) {
resultSb.append(" ");
}
}
System.out.println(resultSb.toString());
}
  
public static int[] reverseArray(int[] originalArray) {
// TODO implement this function
throw new UnsupportedOperationException();

//put code here
}
}
