Need explanations on how this code processes Arraylist values

Question

public static void mystery1(ArrayList list) { 
for (int i = list.size() - 1; i > 0; i--) { 
    if (list.get(i) < list.get(i - 1)) { 
        int el         


        

Answer 1

I think you are forgetting that the loop is going from the end of the list to the beginning. If you take the list you gave as input and follow the process you will get the result [10, 30, 40, 20, 60, 50]. Which is the right one. Just do it in paper and you will see.
