Grouping Anagrams from a Sequence of Words
Sat Mar 23 2024 Anagrams:
This method harnesses the power of sorting and mapping to elegantly categorize anagrams. By iterating over each word in the provided list, it creates a sorted key that represents the word's characters in a uniform order. This key serves as a unique identifier for anagrams, allowing the method to accumulate words with identical keys into groups. Utilizing a Map to maintain these groups ensures that each collection of anagrams is easily retrievable and distinct. The method culminates by outputting these groups, showcasing the anagrams together in a clear and organized manner.
