扑克
1.定义一个数组,存放1-52(分别表示52张扑克,不含大、小王)
其中1表示黑桃A,2表示黑桃2...,13表示 黑桃K,14表示红桃A......)
2.随机排列该数组
3.再将牌平均分给4个玩家(分成4个数组,按照发牌规则)
4.排序输出每个玩家的扑克(先按照花色:黑桃、红桃、梅花,方块;再按照大小)

var arr=[];
//1.在arr数组里存放1-52张牌
for(var i=1;i<=52;i++){
arr[arr.length]=i;
}
//2.洗牌
arr.sort(function(){
return Math.random()-0.5;
});
//3.定义玩家数组
var players=[];
for(var i=0;i<4;i++){
players[i]=[];
}
//4.发牌
for(var i=0;i<52;i++){
//0,4,8
//1,5,9
players[i%4].push(arr[i]);
}
//5.玩家排序
for(var i=0;i<4;i++){
players[i].sort(function(a,b){
return a-b;
});
}
// console.log(arr);
// console.log(players);
//6.输出
var types=["黑桃","红桃","梅花","方块"];
var nums=["A","2","3","4","5","6","7","8","9","10","J","Q","K"];
for(var i=0;i<4;i++){
console.log(‘玩家‘+(i+1)+"的牌：");
for(var j=0;j<13;j++){
var n=players[i][j];
var type=Math.floor((n-1)/13);//n-1对应下标0123
var sno=(n-1)%13;//n-1对应下标0-13
console.log(types[type]+nums[sno]);

console.log(‘==========‘);
