The function should find the smallest (positive) number in the array.
The array can contain the following values:
- Positive number
- Negavitve number
0-
Nullvalue
If no number is found, you should return 0
Note: Zero is also counted as a positive number.
#Examples
[1, 2, 3, 4] => 1
[-2, 0, 4] => 0
[-2, -5] => 0
