数据结构与算法之用队列模拟方块舞

class Queue {

    this.dataStore.push(element)
  }

  //  出列
  dequeue() {

  front() {

  //  队列最后面一个
  back() {

  }

  toString() {
    var retStr = ''
    for (var i = 0; i < this.dataStore.length; i++) {
      retStr += this.dataStore[i] + "\n"
    }
    return retStr
  }

  //  是否为空队列
  empty() {
    if (this.dataStore.length === 0) {
      return true
    } else {
      return false
    }

  //  队列总数
  count() {
    return this.dataStore.length

//  命名一个舞者对象
function Dancer(name, sex) {
  this.name = name
  this.sex = sex

//  站队
function getDancers(males, females) {

//  女性舞者队列
var femaleDances = new Queue()

//  站队
getDancers(maleDancers, femaleDances)

//  1v1分配舞者
dance(maleDancers, femaleDances)

//  分配完以后如果队列不为空，则是没有匹配到舞者的人
if (!maleDancers.empty()) {
