This is a command line program created in order to learn Scala.
It accepts a path to a text file of names as an argument. It prints a score calculated using a simple algorithm.
Execute the program by running sbt "run ./test-names.txt" from the project root.
Run the unit tests by executing sbt test
Create a command line utility that will compute a score for a list of first names.
The list of names will be provided as a text file. The full path to the names file will be specified as a command line argument. The names file will contain a single line of quoted, comma-separated names. A small sample of data can be found in the test-names.txt file.
To score a list of names, you must sort it alphabetically and sum the individual scores for all the names. To score a name, sum the alphabetical value of each letter (A=1, B=2, C=3, etc...) and multiply the sum by the name's position in the list (1-based).
For example, when the sample data is sorted into alphabetical order, LINDA, which is worth 12 + 9 + 14 + 4 + 1 = 40, is the 4th name in the list. So, LINDA would obtain a score of 40 x 4 = 160. The correct score for the sample list is 3194. The correct score for the full data is 871198282.
Keep the following in mind while implementing your design to make future changes easy.
- Another department will want to use this utility as well, but they have a much more complex name scoring algorithm.
- This scoring feature will be added to the company's intranet web-app, allowing employees to upload and score files from their desktop.
- The company will be switching from first names only to both first and last names in the file.
- I made the assumption that lowercasing the names was going to be okay for calculating the score. The input is all in uppercase, but I didn't want to rely on that so I explicitly lowercase.
