Wechat randomly generated red envelope amount algorithm java version

The craziest thing to play in recent years should be sending red envelopes, especially during the new year. The following is a random algorithm for red envelopes. In fact, it is very simple. It only provides an idea and hopes to give you some inspiration.

Later, I collected some wechat random generation red envelope algorithms on the Internet for your reference.

The basic idea here is as follows: first, calculate the average value of the red envelope, and then use a red envelope whose random number of red envelopes is less than the average value. When the red envelope is sent, the total amount of the red envelope needs to be reduced accordingly. At the same time, recalculate the average value: the new total amount% (the original total number of red envelopes - 1), until the last red envelope, insert all the remaining amounts.
