Given a number, for example, like this:

rustlet num: u16 = 12345;

Check that all digits of this number are greater than zero.

Задание 5

Three arrays are given:

rustint arr1: [i8: 5] = [1, 2, 3];
int arr2: [i8: 5] = [4, 5, 6];
int arr3: [i8: 5] = [7, 8, 9];

Combine these arrays into one:

rust[1, 2, 3, 4, 5, 6, 7, 8, 9]

Задание 6

Given a variable with a number:
