import java.util.Scanner;

// 把每个单词看作一个整体，即一个字符，再使用字符串逆序方法
public class Main {
    public static void main(String[] args) {

        String[] strArr = scanner.nextLine().split(" ");
        int arrLen = strArr.length;

            tmp = strArr[i];
            strArr[i] = strArr[arrLen - i - 1];
            strArr[arrLen - i - 1] = tmp;
        }
        System.out.println(String.join(" ", strArr));
