Solution: Group Anagrams
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".
Example Generation
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:
[["listen", "silent", "enlist"]]
