URL Builder

👩‍🎓 NEW GRAD📚RELATED PROBLEMS

Creating URLs dynamically is a common task when dealing with web applications and APIs. Building these URLs correctly ensures that the desired endpoint is reached with the appropriate parameters.

To build a URL, we define a function buildURL that takes a base URL (baseURL), an endpoint (endpoint), and a list of parameters (params) as a list of key-value pairs. The function concatenates the base URL and endpoint, appends a ? character, and adds the parameters in the format key=value separated by the & character. If the params list contains a page attribute, it should be placed at the end of the URL. Otherwise, the parameters should be built into the URL in the order given in params.

Function Description

Complete the function buildURL in the editor.

buildURL has the following parameters:

1. String baseURL: the base URL
2. String endpoint: the endpoint to be appended to the base URL
3. List> params: a list of key-value pairs representing the parameters

Returns

String: the complete URL constructed from the inputs

Example 1:

Input:  baseURL = "https://api.example.com", endpoint = "/data", params = [["type", "user"], ["page", "2"], ["id", "123"]]
Output: "https://api.example.com/data?type=user&id=123&page=2" 
Explanation:
      
      For example, given baseURL = "https://api.example.com", endpoint = "/data", and params = [("type", "user"), ("page", "2"), ("id", "123")], the function should return https://api.example.com/data?type=user&id=123&page=2. Note that the page parameter is moved to the end to ensure it is correctly interpreted by the API.
