给你一个字符串数组,请你将 字母异位词 组合在一起。可以按任意顺序返回结果列表。
字母异位词 是由重新排列源单词的所有字母得到的一个新单词。
示例 1:
输入: strs = ["eat", "tea", "tan", "ate", "nat", "bat"]
输出: [["bat"],["nat","tan"],["ate","eat","tea"]]
示例 2:
输入: strs = [""]
输出: [[""]]
示例 3:
输入: strs = ["a"]
输出: [["a"]]
提示:
1 <= strs.length <= 104
0 <= strs[i].length <= 100
strs[i]
仅包含小写字母- class Solution:
- def groupAnagrams(self, strs):
- res={}
- for st in strs:
- key = "".join(sorted(st))
- if key in res:
- res[key].append(st)
- else:res.update({key:[st]})
- return list(res.values())
-
- strs = ["eat","tea","tan","ate","nat","bat"]
- print(Solution().groupAnagrams(strs))
