ASP.NET实现微信抢红包代码实例
群里都在玩抢红包,抢了再发,发了再抢,简直是无聊,程序员感兴趣是的如何实现,这里简单说说实现思路,附上dome,代码有点low,好在是实现了,具体内容如下
正文
100块发30个红包
50块发13个红包
1块发10个红包
发红包需要满足以下几个条件
1.总金额不变2.每个红包都必须有钱3.尽量的均匀点,不然抢红包没什么意思了
实现思路1.首先要确定最小单位,这里是精确到分,我这里以int类型进行计算,得出的结果也全是int类型2.数据均匀,这里以1<n<(剩余金额/剩余红包数)*2,这里防止一个红包抢走大量的钱,这里需要写个递归,去检查数据值是否过大,50元发13个红包的第3图,就是因为没有检查数据,导致钱不平均,这个可以根据自己的玩法去设置.3.余数处理,当数据平均给20个红包,肯定跟总金额有所偏差,这时候我们就要多退少补,如果大于总金额,让红包金额多的去减少(总金额/总人数),如果还有剩余,就让第二多的去减少,直到补完这个空缺为止,反之亦然.4.打乱顺序,细心的园友可能发现,红包是有顺序规律的,我们必须简单的写个function去打乱它.
