URL Parsing

The challenge requires parsing a sample URL that includes a scheme, authentication info, host, port, path, query params, and query fragment. The parsed URL should be used to extract the individual components of the URL.

Requirements

The url and net packages should be imported.
The sample URL should be parsed and checked for errors.
The scheme, authentication info, host, port, path, query params, and query fragment should be extracted from the parsed URL.
The SplitHostPort function should be used to extract the hostname and port from the Host field.
The ParseQuery function should be used to parse the query params into a map.

Example

## Running our URL parsing program shows all the different
## pieces that we extracted.
$ go run url-parsing.go
postgres
user:pass
user
pass
host.com:5432
host.com
5432
/path
f
k=v
map[k:[v]]
v

Summary

The URL Parsing requires parsing a sample URL and extracting the individual components of the URL. The url and net packages are used to parse and extract the URL components.
