Problem Statement

You are given a list of words or phrases, and you need to group the words that are anagrams of each other. An anagram is a word, phrase, or sentence formed from another word by rearranging its letters.


The input will be a list of words or phrases. The following is an example of input:

{"word", "sword", "drow", "rowd", "iced", "dice"}


The output should be a list of grouped words. The following is an example output:

{{"word", "drow", "rowd"}, {"sword"}, {"iced", "dice"}}

Coding exercise

You need to implement the function groupAnagrams(strs), where strs is the list of words you need to group together. The function returns a list containing multiple lists of the newly created groups.
