Longest Word Test

The Rules

1. Solution may be in any language and use any implementation or algorithm
2. Solution must find the longest word in a corpus. Words are only considered to be space and newline delimited text.
3. Solution is timed from first loading/reading of the corpus to the return of the longest word and/or length of the word.

• Parsing arguments is not counted
• Runtime initialization is not counted
• Time should be measured in MS

Note: Solutions are currently divided into two categories: single-threaded and concurrent.

How to participate

Write your solution, add your name to the top, and send a pull request. It would be super awesome if you also updated the Dockerfile and the run_tests.sh to include your submission, but that's not necessary.
