PROGRAMMING:Switch seats
After the final exam, the automation class had a dinner party, where ZJ and Xiaohui ate at the same table. ZJ wants to sit on the left side of Xiaohui's classmate, so she needs to exchange places with the classmate on Xiaohui's left. For the convenience of solving the problem, suppose there are 10 students at this table, each of them has a seat number (No. 1-10) in their hands, and ask No. 2 to sit on the right side of No. 1, No. 3 to sit on the right side of No. 2... And No. 1 to sit on the right side of No. 10. If we know that ZJ's seat number is n and Xiaohui's seat number is m, what's the seat arrangement after the exchange.
