You are currently in your house wearing your PJ’s. You must get fully dressed and leave the house.
Your challenge is to programmatically process a list of getting dressed commands, enforce related rules, and display appropriate output.
- Temperature type (one of the following)
- HOT
- COLD
- Comma separated list of numeric commands
| Command | Description | Hot Response | Cold Response |
|---|---|---|---|
| 1 | Put on footwear | "sandals" | "boots" |
| 2 | Put on headwear | “sunglasses” | "hat" |
| 3 | Put on socks | "fail" | "socks" |
| 4 | Put on shirt | "shirt" | "shirt" |
| 5 | Put on jacket | "fail" | "jacket" |
| 6 | Put on pants | "shorts" | "pants" |
| 7 | Leave house | "leaving house" | "leaving house" |
| 8 | Take off pajamas | "Removing PJs" | "Removing PJs" |
Regardless of how the program is invoked, the program must take the list of input commands as command line arguments to the program. For example:
./get-dressed HOT 1, 2, 3, 4, 5, 6, 7, 8
- You start in the house with your PJ’s on
- Pajamas must be taken off before anything else can be put on
- Only 1 piece of each type of clothing may be put on
- You cannot put on socks when it is hot
- You cannot put on a jacket when it is hot
- Socks must be put on before footwear
- Pants must be put on before footwear
- The shirt must be put on before the headwear or jacket
- You cannot leave the house until all items of clothing are on (except socks and a jacket when it’s hot)
- If an invalid command is issued, respond with “fail” and stop processing commands
Input: HOT 8, 6, 4, 2, 1, 7
Output: Removing PJs, shorts, shirt, sunglasses, sandals, leaving house
Input: COLD 8, 6, 3, 4, 2, 5, 1, 7
Output: Removing PJs, pants, socks, shirt, hat, jacket, boots, leaving house
Input: HOT 8, 6, 6
Output: Removing PJs, shorts, fail
Input: HOT 8, 6, 3
Output: Removing PJs, shorts, fail
Input: COLD 8, 6, 3, 4, 2, 5, 7
Output: Removing PJs, pants, socks, shirt, hat, jacket, fail
Input: COLD 6
Output: fail
Please submit your solution in Scala and provide all source, test, documentation, and build support files in this repository and email ssteward@rewardsnetwork.com to let us know when you're finished. The project structure is up to you, but assume that this code will be deployed to production and your peers will be maintaining the code going forward.
You will primarily be judged on the code directly related to the implementation of the stated problem and business rules:
- Correct implementation of business rules
- Code Legibility
- Testability
- Ease of Maintenance
- Use of functional programming concepts
- Use of recognizable best practices and patterns
- Submission of a working solution with basic usage instructions
Secondary evaluation criteria include the usage and evident knowledge of the tools, utilities, frameworks, and methodologies specified in the job description.
We value creativity and initiative to learn new technology; however, be advised that candidates that focus solely on the primary criteria will be more successful than candidates that focus instead on intricate interface or usage of a breadth of technologies.
If you do not have professional Scala experience, we will take that into consideration during our assessment.
