49. Group Anagrams

 

Given an array of strings strs, group the anagrams together. You can return the answer in any order.

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.

 

Example 1

Input: strs = ["eat","tea","tan","ate","nat","bat"] Output: [["bat"],["nat","tan"],["ate","eat","tea"]]

 

Example 2

Input: strs = [""] Output: [[""]]

 

Example 3

Input: strs = ["a"] Output: [["a"]]

        for s in strs:
            res[''.join(sorted(s))].append(s)
        return res.values()
