# Anagram clasification

## Concepts
Anagrams are words with exactly the same letters in different order
e.g., AMOR, ROMA, and MORA

## What we need

Write a function that...
- receives an Array of words
- prints the words found in the Array
- each set of anagrams on a line
- separate words with ' - '


## Example
```
//
// Given:
// ['AMOR', 'XISELA', 'JAMON', 'ROMA', 'OMAR', 'MORA', 'ESPONJA', 'RAMO', 'JAPONES', 'ARMO', 'MOJAN', 'MARO', 'ORAM', 'MONJA', 'ALEXIS']

==>  Prints:

// AMOR - ROMA - OMAR - MORA - RAMO - ARMO - MARO - ORAM
// MONJA - JAMON - MOJAN
// ESPONJA - JAPONES
// ALEXIS - XISELA
```
