Given an array of strings strs, group all anagrams together into sublists. You may return the output in any order.
An anagram is a string that contains the exact same characters as another string, but the order of the characters can be different.
Example 1:
Input: strs = ["act","pots","tops","cat","stop","hat"]
Output: [["hat"],["act", "cat"],["stop", "pots", "tops"]]
Example 2:
Input: strs = ["x"]
Output: [["x"]]
Example 3:
Input: strs = [""]
Output: [[""]]
Constraints:
1 <= strs.length <= 10000.0 <= strs[i].length <= 100strs[i] is made up of lowercase English letters.
ExamplesExample 1:
Input: strs = ["act","pots","tops","cat","stop","hat"]
Output: [["hat"],["act", "cat"],["stop", "pots", "tops"]]
Example 2:
Input: strs = ["x"]
Output: [["x"]]
Example 3:
Input: strs = [""]
Output: [[""]]
