Problem Statement

Given a list of strings, the task is to group the anagrams together.

An anagram is a word or phrase formed by rearranging the letters of another, such as "cinema", formed from "iceman"

You can return the answer in any order.

Examples

Example 1:

  • Input: ["dog", "god", "hello"]
  • Output: [["dog", "god"], ["hello"]]
  • Justification: "dog" and "god" are anagrams, so they are grouped together. "hello" does not have any anagrams in the list, so it is in its own group.

Example 2:

  • Input: ["listen", "silent", "enlist"]
  • Output:
