Here’s the PDF of their original paper: https://static.googleusercontent.com/media/research.google.com/en//archive/mapreduce-osdi04.pdf

After reading the paper:
- Provide an one-sentence description of the example code they provide in the paper,
- Provide an example input that might be used with their example code,
- Provide the output of their result to your sample input (it’s a set of key-value pairs, which is easily represented in JSON format)
