The 4 ways a story can end

At the end of a story, the main character(s) will either get what they want and need or they won't. So the 4 possible outcomes are: 

1. get what they want and what they need

2. get what they want but not what they need

3. don't get what they want but get what they need

4. don't get what they want or what they need

#1 is the most common ending. Disney's Aladdin is a good example. Most Disney movies have such an ending. 

Kafka's The Metamorphosis has a #4 ending. 

Finding examples of #2 and #3 are exercises I leave to the reader.
