思想：数组类的使用

代码

import java.util.*;
public class Main{


	public static void main(String[] args){
		Scanner scan = new Scanner(System.in);
		int len = scan.nextInt();
		int n = scan.nextInt();
		
		int[] arr = new int[len];
		for(int i = 0; i < len; i++){
			arr[i] = i+1;
		}
		
		for(int i = 0; i < n; i++){
			int flag = scan.nextInt();
			int index = scan.nextInt();
			if(flag == 0){
				Arrays.sort(arr, 0, index);
				for(int left = 0, right = index-1; left < right; left++, right--){
					int temp = arr[left];
					arr[left] = arr[right];
					arr[right] = temp;
					
				}
			
			}else if(flag == 1){
				Arrays.sort(arr, index-1, len);
			}
		}
		for(int i = 0; i < len; i++){
			System.out.print(arr[i] + " ");
		}
 	}  
}
