49. Group Anagrams

Given an array of strings, group anagrams together.

Example:

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

Output:

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

*All inputs will be in lowercase.

*The order of your output does not matter.

给定一个字符串数组,将字母异位词组合在一起。字母异位词指字母相同,但排列不同的字符串。

示例:

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

输出:

[
  ["ate","eat","tea"],
  ["nat","tan"],
  ["bat"]
]
说明:
  • 所有输入均为小写字母。

  • 不考虑答案输出的顺序。
