Where can I find this chart of possible approaches? Can you add a link in the description?
Of course I could just copy it myself but just checking.

I used the same approach in paypal interview and to be honest the interviewer was not satisfied.
Instead a better approach would be to sort all strings in the given array which makes the all anagrams same string. Add all duplicate strings into separate list and return them.

I have seen the responses where in people have used Arrays.sort and and used the srorted string as key and created the key-list map. It is accepted in LeetCode but do companies have an issue with this solution?
