Application to transform roman numerals to integers.

Roman Numerals Project

Application to transform roman numerals to integers.

Project Objective

Write a Ruby module to operate on roman numerals. Let's keep it all Ruby for now (instead of Rails), and use Rspec for testing.

Follow these steps to submit your code:

1. Ask to have a folder created in the repo with your name.
2. Clone the repository to your computer.
3. Modify the files and commit changes to complete your solution (in your folder).
4. Push/sync the changes up to GitHub.
5. Create a pull request on the original repository to turn in the assignment.

Phase 1 Objective

Write a Ruby module to transform roman numerals to integers.

Examples

VII -> 7
XVI -> 16
LX -> 60

---

Phase 2 Objective

Expand your program to also do the reverse, transform integers into roman numerals.

Examples

7 -> VII
16 -> XVI
60 -> LX

---

Phase 3 Objective

Download 3Hub or some other file viwer and configure with AWS credentials.

1. Use the CSV library to read some roman numerals from a file and transform them into integers.
2. Read the file from a bucket in S3: (s3://sktraining.s3.amazonaws.com/roman_numerals/roman_numeral_sample.txt).
3. Write results to a file in a bucket in S3: (s3://sktraining.s3.amazonaws.com/roman_numerals/YOURNAME).

Sample Input File

VII
IX

Phase 4 Objective

1. Write a program that can perform math on roman numerals.
2. Read an input file of operations from S3 (s3://sktraining.s3.amazonaws.com/roman_numerals/roman_numeral_sample_operations.csv).
3. Write results to a file in a bucket in S3: (s3://sktraining.s3.amazonaws.com/roman_numerals/YOURNAME).
