An array of strings strs is given. Group the anagrams together.

The answer may be returned in any order.

Example 1

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

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

Explanation

There is no string in strs that can be rearranged to form "bat".

The strings "nat" and "tan" are anagrams because their characters can be rearranged to form each other.

The strings "ate", "eat", and "tea" are anagrams because their characters can be rearranged to form each other.

Example 2

Input: strs = [""]

Output: [[""]]

Example 3

Input: strs = ["a"]

Output: [["a"]]
