(1/2) extract one number from the numbers 1, 2, and 3 twice without replacement, and use (x, y) to represent "Number x for the first time, the second time, the number is y"

This is equal to two
So it is 6.
 
, 5 digits 1 2 3 4 5 The first transfer is to put the numbers on both sides to the right, the second move the numbers on both sides to the left, the third

Tested: the first question is no solution, and it will never be less than 54321
The second question changes to 12345 every six cycles.
