public static void main(String[] args) {
final int M = 6; // number of girls，可改动
final int N = 7; // number of boys，可改动
int x = 3;// some boy，可改动
int y = 5;// some girl，可改动
String result = "";// 记录结果，即第二个问题
// 初始化，假设队列存放男女生编号，从1开始
QueueInteger boys = new LinkedListInteger();
for (int i = 1; i = N; i++) {
boys.add(i);
}
QueueInteger girls = new LinkedListInteger();
for (int i = 1; i = M; i++) {
girls.add(i);
}
// 跳舞开始
int min = boys.size() girls.size() ? girls.size() : boys.size();
int k = 1;// songs
int count = 2; // 求出两个值，可改动
while (k 1000) {//为了不死循环，这里假设最多有999支舞蹈
System.out.println("***This is the " + k + "st dance:");
for (int i = 0; i min; i++) {
// 跳舞，第一个问题：输出每曲配对情况
System.out.println("Boy " + boys.peek() + " = Girl "
+ girls.peek());
// 跳过的排到对尾
int boy = boys.remove();
boys.add(boy);
int girl = girls.remove();
girls.add(girl);
// 判断 x和y跳舞了没有
if (boy == x girl == y) {
result += k + ",";
count--;
}
}
if (count == 0)
break;
// next dance
k++;
}
// 结果
if (count == 0)
System.out.println("\n***Boy " + x + " and Girl " + y
+ " dance together in : " + result);//第二个问题的解答，跳了哪几支舞
else
System.out.println("\n***Boy " + x + " and Girl " + y
+ " have no chance to dance!");//第二个问题的解答，两人没机会跳舞
}
请用java语言设计程序实现：假设舞会上男女生各自一排，每次排头牵手跳舞
6 5 1 2 结果才是6；男排 女排 男序号 女序号
。。。。。。。。。。。。。。。。。。。。。。。。。
package net;
import java.util.Scanner;
public class Test {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
System.out.println("请输入男排人数：");
int boyArray = sc.nextInt();
System.out.println("请输入女排人数：");
int girlArray = sc.nextInt();
System.out.println("请输入男生序号：");
int boy = sc.nextInt();
System.out.println("请输入女生序号：");
int girl = sc.nextInt();
int count=0;
for(int i=1;i=boyArray*girlArray;i++){
if(iboyArray||igirlArray){
if(i==boyi==girl){
count=i;
System.out.println("该对男女第一次牵手跳舞的序号是a："+i);
break;
}
}
else if((i%boyArray==boy)(i%girlArray==girl)){
count=i;
System.out.println("该对男女第一次牵手跳舞的序号是："+i);
break;
}
}
if(count==0){
System.out.println("该对男女不可能一起跳舞！");
}
}
}
数据结构中的舞伴问题。用JAVA实现
/**
假设在周末舞会上，男士们（m人）和女士们（n人）进入舞厅时，各自排成一队。跳舞开始时，依次从男队和女队的队头上各出一人配成舞伴。若两队初始人数不相同，则较长的那一队中未配对者等待下一轮舞曲。现要求写一算法模拟上述舞伴配对问题。并m和n存在什么条件时，第x个（1 =x =m）男生才有可能和他心仪的第y个（1 =x =n）女生跳舞，在第几首曲子时？
