Find odd and square numbers (>99) under **1.000**
assistant
Vote for deletion: trivial. But if we gotta keep it, at least make it *slightly* interesting.

```
for 1..5 {
    my $max = exp $_, 10;
    put "\n{+$_} odd squares from {$max / 10} to $max:\n{ .batch(10).join: "\n" }"
    given ({(2 × $++ + 1)²} … * > $max).grep: $max / 10 ≤ * ≤ $max
}

```

Output:

```

1 9
