Language/Type: Java ArrayList Collections mystery
Author: Roy McElmurry

Consider the following method:

public static void mystery2(ArrayList<Integer> list) { 
    for (int i = list.size() - 1; i > 0; i--) { 
        if (list.get(i) < list.get(i - 1)) { 
            int element = list.get(i); 
            list.remove(i); 
            list.add(0, element); 
        } 
    } 
    System.out.println(list); 
}

Write the output produced by the method when passed each of the following ArrayLists:

[2, 6, 1, 8]
[30, 20, 10, 60, 50, 40]
[-4, 16, 9, 1, 64, 25, 36, 4, 49]
