API that categorizes and stores numbers based on their divisibility
Go is an open source programming language that makes it easy to build simple,
reliable, and efficient software.
Tip
Implement an API that categorizes and stores numbers based on their divisibility by 3 and 5, mimicking the logic described below:
- Numbers divisible by 3: Categorized as "Type 1"
- Numbers divisible by 5: Categorized as "Type 2"
- Numbers divisible by both 3 and 5: Categorized as "Type 3"
- Other numbers: Stored as their original value
Caution
Utilize only one if statement within the core logic. Avoid else, else if, ternary operators, or switch statements.
Note
The API shall store numbers and their classifications in memory or any other support you consider appropriate.
- Numbers divisible by 3: Categorized as "Type 1"
- Numbers divisible by 5: Categorized as "Type 2"
- Numbers divisible by both 3 and 5: Categorized as "Type 3"
- Other numbers: Stored as their original value
POST localhost:8080/numbers/ The API provides a mechanism to save a number into its collection.
name type data type description number required object (JSON) {"number":25}
http code content-type response 201application/jsonCreated successfully400application/json"message": "There was an error processing the request!"
GET localhost:8080/numbers/{number} The API allows the retrieval of a specific number's classification. If
the number is not found, the API returns 404

http code content-type response 201application/json{"Number": 25,"Category": "Type 2"}404application/json"message": "number not found"400application/json"message": "Can't convert this to an int!"
GET localhost:8080/numbers The API enables the retrieval of all stored numbers and their classifications.
