the sample test case is passed but all other test cases got failed

Scanner sc = new Scanner(System.in); int n = sc.nextInt();

    List<Integer> l = new ArrayList<>(n);
    for(int i =0; i<n; i++){
        l.add(sc.nextInt());
    }
    int q = sc.nextInt();
    sc.nextLine();
    for(int i =0; i<q; i++ ){
        String str = sc.nextLine().trim();
         if(str.equalsIgnoreCase("Insert")){
            int index = sc.nextInt();
            int value = sc.nextInt();
            sc.nextLine();
        l.add(index,value);
    } 
    if(str.equalsIgnoreCase("Delete")){
            int removeindex = sc.nextInt(); 
             l.remove(removeindex);
       }
    }
       l.forEach(l1 -> System.out.print(l1 + " "));
