import java.util.Scanner;

public class DecreasingOrNot {

    public static void main(String[] args){
        int number1, number2;
        boolean decrease = true;
        Scanner input = new Scanner(System.in);
        System.out.println("Enter a sequence of numbers: ");
        number2 = input.nextInt();
        while (decrease && input.hasNext()){
            number1 = number2;
            number2 = input.nextInt();
            if (number1 < number2){
                decrease = false;
            }
        }
        if (decrease){
            System.out.println("Yes");
        }
        else{
