Approach-2 Summary : It utilizes a hash map to categorize strings based on their character frequencies. The generate method converts a string into a unique representation by counting the occurrences of each character and creating a sorted string. The main groupAnagrams function iterates through the input strings, generates their unique representations, and uses the hash map to group anagrams together. The result is a list of lists, where each inner list represents a group of anagrams.
