This is the 12th Video of our Playlist "Arrays 1D/2D : Popular Interview Problems".
In this video we will try to solve two very good and frequently asked Array problem - Group Anagrams | Leetcode 49
We have already solved this Problem using sorting in our 11th Video of this playlist. Check it out here -    • Group Anagrams | without sorting | Google ...  

I will explain the intuition so easily that you will never forget and start seeing this as cakewalk EASYYY.
We will do live coding after explanation and see if we are able to pass all the test cases.
Also, please note that my Github solution link below contains both C++ as well as JAVA code.

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.
