Application of cyclic queue-partner pairing problem: At the party, the men and women are each lined up in a team. At the beginning of the dance, one of the men and the women's team was paired up with a partner. If the initial number of teams is not equal, the longer team is not paired to wait for the next round of dance. Assuming that the initial male, female and gender has been fixed, the number of rounds of the ball is entered from the keyboard. Try to solve the above partner pairing problem. Requirements: Output each round of partner pairing list from the screen, if there is an unpaired in the round, the name of the unpaired who is able to display the next round of the first appearance from the screen.
