Prime Pandigital Step Numbers
Public  05/12/17  6xp  Programming  64.7% 
A step number is a number whose digits are in ascending order
For example : $ 1223455567 $ is a step number
A pandigital step number is a step number which contains all digits (except 0) at least once
For example : $ 1122345556777899 $ is a pandigital step number
Find the smallest $(S)$ and largest $(L)$ 30digits prime pandigital step numbers
Answer format: S,L
Example: 111111111111223456789,123456777788888888899 // For 21 digts
