Write a recursive method using Java that takes a string s as input and returns a list that contains all the anagrams of the string s. An anagram is a word formed by rearranging the letters of a different word. For instance, the word ‘cat’ is an anagram of ‘act’. Notice that the output list cannot contain duplicates.
