For example, say I have string like:

duck duck duck duck goose goose goose dog

And I want it to be as sparsely populated as possible, say in this case

duck goose duck goose dog duck goose duck

What sort of algorithm would you recommend? Snippets of code or general pointers would be useful, languages welcome Python, C++ and extra kudos if you have a way to do it in bash.
