Find and show here all positive integers **n** less than **100** where:

* the sum of the digits of the square of **n** is prime; and
* the sum of the digits of the cube of **n** is also prime.

Example

**16** satisfies the task descrption because 16 x 16 = 256 has a digit sum of 13 which is prime and
16 x 16 x 16 = 4096 has a digit sum of 19 which is also prime.

```
say ^100 .grep: { .².comb.sum.is-prime && .³.comb.sum.is-prime }

```

Output:
