Group Anagrams | SOLUTION WALKTHROUGH - Hashmap

LINK TO PROBLEM: leetcode.com/p...
yo!!!! this one's a little bit interesting - we're using python tuples as keys to our dictionary/hashmap. along with that, we're using an array of length 26 to denote how many of each character are in a word.
these are very useful ideas/tricks to remember for other leetcode problems. please let me know if you have any questions!!!

if you're using java/javascript/whatever language, the alternative to the tuple is to turn the "pattern" array into a string! just make sure you separate each character count with a delimiter, like "#".
