Codewars Bar recommends you drink 1 glass of water per standard drink so you're not hungover tomorrow morning.
Your fellow coders have bought you several drinks tonight in the form of a string. Return a string suggesting how many glasses of water you should drink to not be hungover.
"1 beer" => "1 glass of water"
"1 shot, 5 beers and 1 glass of wine" => "7 glasses of water"
- To keep the things simple, we'll consider that anything with a number in front of it is a drink:
"1 bear" => "1 glass of water"or"1 chainsaw and 2 pools" => "3 glasses of water" - The number in front of each drink lies in range
