2023-6: Key/Value Pairs

Representing data as key/value pairs (also known as name/value pairs) is a very common technique. For example, it can be found in query strings in HTTP URIs, attribute settings in HTML elements, and in JSON objects. One common representation for a key/value pair is to have a character key (name) followed by an equals sign (=) followed by the value. Multiple key/value pairs can be separated by a delimiter character or characters. For example:

key1=value1;key2=value2

Write code that:

takes a 2-element character vector first argument where the first element represents the separator character between multiple key/value pairs and the second element represents the separator between the key and the value for each pair.

takes a character vector second argument representing a valid set of key/value pairs (delimited as specified by the first argument).

returns a 2-column matrix where the first column contains the character vector keys of the key/value pairs and the second column contains the character vector values.

Note: You may assume that there will be no empty names or values in the second argument.
