Macro b_tree_set

macro_rules! b_tree_set {
    () => { ... };
    ($($elem:expr),*) => { ... };
}

Creates a new BTreeSet<T>.

This macro provides two ways to initialize a BTreeSet:

1. Empty Set:

   • Calling b_tree_set!() creates an empty BTreeSet.

2. With Elements:

   • You can also initialize a BTreeSet with elements by providing a comma-separated list of values, e.g., b_tree_set!(1, 2, 3).
   • This will create a BTreeSet containing the specified elements.
