Question

Given an array of strings strs, group the anagrams together. You can return the answer in any order.

An Anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.

Example 1:

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

Example 2:

Input: strs = [""]
Output: [[""]]

Example 3:

Input: strs = ["a"]
Output: [["a"]]

Constraints:

• 1 <= strs.length <= 104
• 0 <= strs[i].length <= 100
• strs[i] consists of lowercase English letters.

Python Solution

class Solution:
    def groupAnagrams(self, strs: List[str]) -> List[List[str]]:
        d={}
        result = []

        for i in strs:
            if str(sorted(i)) in d:
                d[str(sorted(i))].append(i)
            else:
                d[str(sorted(i))]=[i]

        for i in d:
            result.append(d[i])

        return result
