For each of the methods you wrote in Lab 2, figure out the time complexity of the method you wrote. To turn in this portion, attach a printout of the code and specify the time complexity of each. import java.util.ArrayList; import java.util.Collections; import java.util.Comparator; import java.util.List; public class Main { // checking for unique list private static boolean unique(List list) { for (int i = 0; i < list.size() - 1; i++) { for (int j = i + 1; j < list.size(); j++) { // checking whether there is mutilpe values or not if (list.get(i).equals(list.get(j))) return false; } } return true; } // checking for mutiples from the list private static List allMultiples(List list, int num) { List newList = new ArrayList<>(); for (Integer i : list) { // checking if num is mutiple of list element if ((i % num) == 0) newList.add(i); } return newList; } // finding size of the given length size string private static List allStringOfSize(List list, int length) { List newList = new ArrayList<>(); for (String str : list) { // checking for list element which of given length if (str.length() == length) newList.add(str); } return newList; } // chekcing for permutation private static boolean isPermutation(List list1, List list2) { // if size of bith list differe return false if (list1.size() != list2.size()) return false; // using comparator for sorting Comparator comp = new Comparator() { @Override public int compare(E o1, E o2) { return o1.toString().compareTo(o2.toString()); } }; // sorting the list Collections.sort(list1, comp); Collections.sort(list2, comp); // checking for permutation for (int i = 0; i < list1.size(); i++) { if (!list1.get(i).equals(list2.get(i))) return false; } return true; } // convert String to list of words private static List stringToListWords(String str) { List words = new ArrayList<>(); String[] ar = str.split(" ");// spliting list into array for (String i : ar) { words.add(i.replaceAll("\\p{Punct}", ""));// adding words to the list after remove all punctuation } return words; } // removing all given instance from the list private static void removeAllInstances(List list, E item) { for (int i = 0; i < list.size(); i++) { if (list.get(i).equals(item))// chekcing for matching instance list.remove(i);// removing it from the list } } }
