Implement this function
import java.util.ArrayList; public interface PermuteAL { ** * Creates a sequence of numbers. Thus, sequence(3) generates [0,1,2]. ArrayList<Integer> sequence(int n); /** * Permute the elements of the array. Step 1: if the size of the input array, arr, is 1 來 add it to the result and return it. Done. * Step 3: for each element i of the list arr, create a new and smaller list, sm, with that element removed. To copy a ArrayList, you can pass it into the constructor of ArrayList. The code below copies arr into sm. <pre> ArrayList<Integer> sm = new ArrayList<>(arr); </pre> Step 3: call permutation on the smaller list and store the result in ires. Step 4: for each list in ires, create a new list by appending the element i of arr. Add the return value of append to result. Step 5: return the result. * / ArrayList<ArrayList<Integer>> permutation(ArrayList<Integer> arr); DELL
