The gut tracker

You will place the parts of the alimentary canal in their regions, add the times that food spends in the parts, and find the part where the food stays longest.

The idea. The alimentary canal has a foregut, a midgut and a hindgut. The times in this lab are made up.

Your tasks.

1. Finish region. It gives "foregut", "midgut" or "hindgut" for a part, using the dictionary.
2. Finish total_time. It gives the sum of the times in minutes.
3. Finish longest. It gives the name of the part with the longest time.
