Selection sort

Solution 1:

sub selection_sort ( @a is copy ) {
    for 0 ..^ @a.end -> $i {
        my $min = [ $i+1 .. @a.end ].min: { @a[$_] };
        @a[$i, $min] = @a[$min, $i] if @a[$i] > @a[$min];
    }
    return @a;
}

my @data = 22, 7, 2, -5, 8, 4;
say 'input  = ' ~ @data;
say 'output = ' ~ @data.&selection_sort;

Output:

input  = 22 7 2 -5 8 4
output = -5 2 4 7 8 22

Solution 2:

sub selectionSort(@tmp) {
    for ^@tmp -> $i {
        my $min = $i; @tmp[$i, $_] = @tmp[$_, $i] if @tmp[$min] > @tmp[$_] for $i^..^@tmp;
    }
    return @tmp;
}

Output:

input  = 22 7 2 -5 8 4
output = -5 2 4 7 8 22
