Interview Course Based on Story Questions

# 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.


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

```python
["word", "sword", "drow", "rowd", "iced", "dice"]
```

## Output

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

```python
[['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.
