You didn't define the value of the reversed s in rules 5 and 6. Is it supposed to be the number of steps? Also rule 5 only applies if both numbers are equal because both are n. For different numbers make it n and m or something like that.

Oh and it also only applies for two entries. Ypu should add a k to the left if you solve from the right or a k to the right if you solve from the left.
