Given an array of strings, remove each string that is an anagram of an earlier string, then return the remaining array in sorted order.

str = ['code', 'doce', 'ecod', 'framer', 'frame']

• code and doce are anagrams. Remove doce from the array and keep the first occurrence code in the array.
• code and ecod are anagrams. Remove ecod from the array and keep the first occurrence code in the array.
• code and framer are not anagrams. Keep both strings in the array.
• framer and frame are not anagrams due to the extra r in framer. Keep both strings in the array.
• Order the remaining strings in ascending order: ['code','frame','framer'].
