This Golang application calculates the optimal number of packs required to fulfill an order, given a set of pack sizes. The application adheres to the following constraints:
Only whole packs can be shipped. The minimum number of items should be shipped. The minimum number of packs should be used. The application includes a basic HTTP API and can include a simple UI for interacting with the calculation logic. Pack sizes are configurable for flexibility.
Go Gin framework (Optional) HTML template engine Installation
Clone the repository. Install dependencies using go mod tidy.
Pack sizes are defined in a JSON configuration file (config.json by default). The file should contain a JSON array of pack sizes:
[
{ "size": 5000 },
{ "size": 2000 },
{ "size": 1000 },
{ "size": 500 },
{ "size": 250 }
]Send a GET request to /packs?quantity=<order_quantity> to get the pack breakdown. Example: curl http://localhost:8080/packs?quantity=1250
Access the UI at http://localhost:8080 Enter the order quantity and submit the form.
Unit tests are included in the test package. Run tests using go test -v.
