Subject: Re: Write a method which takes in a string and returns an array of pairs

Sounds like fun, I'll have a go since I've never done something like 
that before...

Here's one way to do it. If this is homework then you'd better be able 
to explain to your teacher how it works; so I recommend doing some 
studying of the objects and methods involved: "String#scan", "Regexp", 
"Capturing Groups", "Enumerable", "Array", and "String#length"

'moossse'.scan(/(\w)(\1*)/).map{|a,b|[a,b.length+1]}
