/// Sort an array using selection sort
///
/// # Parameters
///
/// - `arr`: A vector to sort in-place
///
/// # Type parameters
///
/// - `T`: A type that can be checked for equality and ordering e.g. a `i32`, a
///     `u8`, or a `f32`.
///
/// # Examples
///
/// ```rust
/// use algorithmplus::sort::selection_sort;
/// 
/// let mut ls = vec![3, 2, 1];
/// selection_sort(&mut ls);
/// 
/// assert_eq!(ls, [1, 2, 3]);
/// ```
