7/// Your goal is to write a function that removes the first and last
8/// characters of a string. You're given one parameter, the original string.
9/// Important: Your function should handle strings of any length ≥ 2 characters.
10/// For strings with exactly 2 characters, return an empty string.
11/// # Example
12/// ``` remove_char("eloquent"); ``` <br>
13/// returns "loquen"
14pub fn remove_char(s: &str) -> String {
15    let kata = Kata {
16        level: Level::L8kyu,
17        tags: vec![Tag::Strings, Tag::Fundamentals],
18        description: String::from("Remove First and Last Character"),
19    };

29/// Implement a function which convert the given boolean value into its
30/// string representation.
31/// # Example
32/// ``` boolean_to_string(true); ``` <br>
33/// returns "true"
