321

132

Answer 1

123 and 321 are easy, forward and backward for loops

The others you will need an if in the for loop

Answer 2

Hey mate,

Are you sure the third entry is meant to be 213 as opposed to 231, the reason I ask is that outside of that entry the pattern of shifting the integers to the left using modulae arithmetic appears to be in action, whilst with that said if it is an error the process continues through,

if you could send the full question, I would be more than happy to provide a full solution,

Regards,

David
