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.
class Solution:
def groupAnagrams(self, strs: List[str]) -> List[List[str]]:
record = dict()
for s in strs:
record.setdefault(''.join(sorted(s)), []).append(s)
ans = [v for v in record.values()]
return ans
