Explanation:

public class Test2 {

public static void main(String[] args) {

   Scanner sc = new Scanner(System.in);

   int N = sc.nextInt();

   sc.nextLine();

   String[] strArr = new String[N];

   for (int i = 0; i < N; i++) {

       strArr[i] = sc.nextLine();

   }

   System.out.println(fun(strArr));

}

public static int fun(String[] arr) {

   TreeSet<String> treeSet = new TreeSet<>();

   for (int i = 0; i < arr.length; i++) {

       char[] chars = arr[i].toCharArray();

       Arrays.sort(chars);

       treeSet.add(chars.toString());

   }

   return treeSet.size();
