Java數(shù)據(jù)結(jié)構(gòu)跳舞配對(duì)問(wèn)題（隊(duì)列的應(yīng)用）

代碼如下，可以直接運(yùn)行。

final int N = 7; // number of boys，可改動(dòng)

int x = 3;// some boy，可改動(dòng)

int y = 5;// some girl，可改動(dòng)

String result = "";// 記錄結(jié)果，即第二個(gè)問(wèn)題

// 初始化，假設(shè)隊(duì)列存放男女生編號(hào)，從1開始

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);

}

// 跳舞開始

int min = boys.size() girls.size() ? girls.size() : boys.size();

int k = 1;// songs

int count = 2; // 求出兩個(gè)值，可改動(dòng)

while (k 1000) {//為了不死循環(huán)，這里假設(shè)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，第一個(gè)問(wèn)題：輸出每曲配對(duì)情況

System.out.println("Boy " + boys.peek() + " = Girl "

+ girls.peek());

// 跳過(guò)的排到對(duì)尾

int boy = boys.remove();

boys.add(boy);

int girl = girls.remove();

girls.add(girl);

// 判斷 x和y跳舞了沒(méi)有

if (boy == x girl == y) {

result += k + ",";

count--;

}

}

if (count == 0)

break;

// next dance

k++;

}

// 結(jié)果

if (count == 0)

System.out.println("\n***Boy " + x + " and Girl " + y

+ " dance together in : " + result);//第二個(gè)問(wèn)題的解答，跳了哪幾支舞

else

System.out.println("\n***Boy " + x + " and Girl " + y

+ " have no chance to dance!");//第二個(gè)問(wèn)題的解答，兩人沒(méi)機(jī)會(huì)跳舞

}

數(shù)據(jù)結(jié)構(gòu)中的舞伴問(wèn)題。用JAVA實(shí)現(xiàn)

/**

假設(shè)在周末舞會(huì)上，男士們（m人）和女士們（n人）進(jìn)入舞廳時(shí)，各自排成一隊(duì)。跳舞開始時(shí)，依次從男隊(duì)和女隊(duì)的隊(duì)頭上各出一人配成舞伴。若兩隊(duì)初始人數(shù)不相同，則較長(zhǎng)的那一隊(duì)中未配對(duì)者等待下一輪舞曲。現(xiàn)要求寫一算法模擬上述舞伴配對(duì)問(wèn)題。并m和n存在什么條件時(shí)，第x個(gè)（1 =x =m）男生才有可能和他心儀的第y個(gè)（1 =x =n）女生跳舞，在第幾首曲子時(shí)？
