Input: strs = ["eat","tea","tan","ate","nat","bat"]
Output: [["bat"],["nat","tan"],["ate","eat","tea"]]
We wll take the string sort it and check if it is already ut in a hashmap, if not
we will put it in a hasmap and check if the other string encountered aligns with the string, if yes, we will put it as a value
of the sorted string in a hashmap. Finally we will print all the values
Time Complexity: O(nklogk)- where k is the length of the string and n is the input string size
space:O(n)
