Solution: Split into even and odd

Here is a possible solution to the task.

Code

my @numbers = 1..10;

my @even = @numbers.grep(* %% 2);
my @odd  = @numbers.grep(* % 2);

say "even: @even[]";
say "odd: @odd[]";

🦋 You can find the source code in the file even-odd.raku.

Output

even: 2 4 6 8 10
odd: 1 3 5 7 9

Comments

* %% 2 is true for numbers divisible by two; * % 2 is true when the remainder is non-zero, i.e. odd. Each grep keeps one group.
Interpolating @even[] with the empty-bracket zen slice prints the elements separated by spaces inside the double-quoted string.
