package FushiExam;
import java.util.*;
public class Text_15 {

    public static void main(String[] args) {
        // 输入三个整数x,y,z,请把这三个数由小到大输出
        Scanner scan=new Scanner(System.in);
        int a=scan.nextInt();
        int b=scan.nextInt();
        int c=scan.nextInt();
        int t;
        if(a>b) {
            t=a;
            a=b;
            b=t;
        }
        if(a>c) {
            t=a;
            a=c;
            c=t;}
        if(b>c) {
            t=b;
            b=c;
            c=t;
            }
        System.out.println(a+"<"+b+"<"+c);
    }
