You have been given an array/list of strings 'STR_LIST'. You are supposed to return the strings as groups of anagrams such that strings belonging to a particular group are anagrams of one another.

Note :

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase. We can generalize this in string processing by saying that an anagram of a string is another string with the same quantity of each character in it, in any order.

Example:

{ “abc”, “ged”, “dge”, “bac” } 
In the above example the array should be divided into 2 groups. The first group consists of { “abc”, “bac” } and the second group consists of { “ged”, “dge” }.
